8 Planet Motorized Orrery - 3D Printed
by Widgetwizard
For those not familiar with what an Orrery is I would (84.01 years) like to o er a brief description. It is an apparatus used to illustrate the relative motion and sizes of planets to Neptune- Orbits the Sun once every 60,190.03 days each other and their orbits around the sun. To put the (164.79 years) orbit times in perspective I have listed the times for the planets below. The planetary orbits around the Pluto- Orbits the Sun once every 90,553 days (247.91 sun are in days/years. years)
Mercury- Orbits the Sun once every 87.97 days (.24 After discovering what an Orrery is I was surprised to years) nd that a 3d printed version of any size was not common. I would like to mention that Dragonator has Venus- Orbits the Sun once every 224.7 days (.61 years) a nice 3D printed Orrery on Instructables. There are many nely crafted brass Orrerys available for Earth- Orbits the Sun once every 365.26 days (1 year) purchase if you are so inclined to purchase one. I had discovered some very nice wooden Orrerys available Moon- Orbits the Earth once every 27.32 days (13.37 as well. What I also discovered is how coveted the times per year) information is on how to make one. The craftsman who design these things do not like to share their Mars- Orbits the Sun once every 686.98 days (1.88 information, particularly on what gear ratios they use years) achieve the correct relative planetary orbits around the sun. To speed this process up I created an Excel Jupiter- Orbits the Sun once every 4,332.82 days spreadsheet. To quickly change ratios I merely had to (11.86 years) change the number of teeth in any or all of the appropriate cells and a ratio was calculated instantly. Saturn- Orbits the Sun once every 10,755.7 days (29.45 This saved an unbelievable amount of time. For years) anyone interested in playing with this I have included it in this instructable. Enjoy! Uranus- Orbits the Sun once every 30,687.15 days

Step 2: 3D Printed Parts Discussion
This project is not for the faint of heart. There are over parts. 3D printed parts in general are not super 100 parts used in the build of this Orrery. One of my precise. I designed the parts with the exact hole size goals in designing this project was to build it as large knowing that they would be slightly smaller. It was as I could (within reason) using a 200mm x 200mm important to have a nice t for the brass tubes. All of print bed. The actual print bed size is larger than this. the other holes in the gears and frames on the driver As you can see from the photo I pushed the limits of side as well as the secondary gears are 1/4". M ake the printer with the frames and the Mercury driver sure t o run t he bit t hrough t he part s gear. You may or may not be able to move your limit st raight , ot herwise your gears may wobble. switches enough to use the entire print bed. I printed these parts on one of my DIY printers and could move You will notice that the printed parts for the motor the limit switches out further. If necessary there are and mounting brackets are di erent than what the many companies out there that can print these for video shows. The motor itself is also di erent. When I you for a reasonable cost. Pay close attention to the made this originally I used a motor I had laying parts as you import them into your printing/slicing around. When I decided to post this I knew I would software. Some of the frames for example have have to buy something so I could provide the part spacers incorporated in them so that side will need to number and information to order it by. be faced up. Some of the gears are compound gears (2 gears in one part). They will also need to be I have tried very hard to make sure that the ts are positioned correctly. good and minimal work will be needed in cleaning the parts. I would however like to make you aware With a couple of exceptions I printed all of the parts that the gear teeth will need a little cleaning up on at 50% ll. Feel free to try a di erent amount. The the print bed side, especially if you use larger print exception to this were the gear spindles. I printed nozzle sizes. Since you want good adhesion of your these at 100% because I wanted the strength. Caution part to the print bed the rst layer is usually squished here, if you print only one or two at a time the parts down pretty good. This will create a raised area along may not have enough time to cool a little between the teeth. If you are having issues with warping and layers and they may sag. Use a cooling fan, slow the use a brim around the edge you will of course need to print speed down or print a few extra spares. The clean the edges up. Since it is important the gear added number of parts will also allow more time teeth mesh well this will need to be cleaned up a bit. I between layers. The planets can be printed 20-30% ll. like to use a utility knife by scraping it (not cutting) The lighter they are the less sagging of the longer along the edge of my parts. I have added a radius planet support rods you will have. I also recommend along the edges to help some with cleanup. using supports enabled when printing to improve the way they look on the bottom side.

It notice in the video I have printed each planet, planet was 6mm in diameter. You can use anything that is arm and gears the same color. I thought it would be approximately this size. Remember that you will have nice to see which gears were actually driving each of to drill a small hole in it for the support. the planets. You certainly do not have to do this, I just thought I would mention it. I used drill bits to clean-up the holes in the printed

Step 5: Driven Gears- Mercury to Mars
8 Planet Motorized Orrery - 3D Printed: Page 6 It is now time to prepare the brass tubes for the gears will occur. You can try epoxy alone however I do not on the driven side. If you have not done so already it is recommend it with the exception of a couple of time to cut the brass tubes to the lengths speci ed on planets. These will be addressed later. For the Sun the "Cut Chart" located in the materials section. The tube place the bead at the very end of the tube. Do tubes needed in this section are Mercury, Venus, Earth not exceed 1/8 distance from end. The Sun tube will and Mars. be inserted 1/8" into the bottom frame. This will be done later. See the photos above for solder reference . It is important that the gears are attached to the tubes in a manner that will not allow the gear to spin Once the glue has set for the "Driver Gears- Mercury on the tube. There are a couple of ways to address To Mars" it is time to assemble the "Driven Gears- this. Use epoxy only or solder a small bead on the side Mercury To Mars" as well as the Sun. Glue spacers to of the brass tube that will act as a key to prevent the bottom of the mating gear. Be careful not to get slipping. The bead is placed so that it will be glue in the end of the tubes. Insert the appropriate approximately in the center of the gear body. Using a tubes into mating gears/spacers.

Hi and many thanks for your time and effort to make this. Im most of the way through the printing. Im having a few problems, Ive read the comments but none of the suggestions work:- 1 - Saturn DRIVER gear top and bottom spacer is not in the zip file 2 - Earth ring bottom spacer is importing massive into Cura slicer, see pic, maybe it is in inches rather than mm, i know cura dosent like inches. Have the dimensions if you cant recreate the problem. Im using windows. Thanks very much, Im making this as a present for my son who has worked hard in his exams and hoping to study astro biology at UCL in London. Results in a month so fingers crossed I can build in time! So grateful for your design and sharing it.
8 Planet Motorized Orrery - 3D Printed: Page 21 Hello again I have added the Saturn Driver Gear Top and Bottom spacers. If you have any other issues please let me know. Sorry again for the missed items. Thanks so much, I'll post a pic when dome
Hello veedubhowarth It has been a long time. I lost my original cad dwg some time ago (computer crash). I will try to measure spacers on mine and post the files. As far as the Earth Ring Bottom Spacer it is actually 2" dia. (50.8mm) x 1/8" (3.2mm) thick. Multiply 199.9859 x .254 = 50.8mm so change your scale factor percentage to 2540 and see what that looks like. Sorry for the missing parts. I have learned a valuable lesson doing this project!!! Triple check before releasing. LOL Hi thanks so much for replying, I think with the amount of parts you created, we will forgive a couple of missing parts!!
I'll post pics when done, thanks a lot. Just printing the frame spacers now
Thank you!
Hi, great project. Ive purchased all the hardware needed and i'm half through printing the parts. The download doesn't include 0.5 Frame Spacer, 0.9 Gear Spindle, 1.00 Neptune Gear Spindle, Saturn Driver gear Top & Bottom spacers (although i see these are the same as for Neptunes), Saturns ring (I believe you made this with paper an laminate). The first 3 are important. I hope you still check these posts as the project is a few years old. Thank you for the project. Hello I opened the zip file for the 3D printed files and the .5 Frame Spacer and the .9 Gear Spacer are there. They are the first 2 items. The Saturn Driver Gear Top and the Bottom Spacer were also there. Not sure why you do not have them. The 1.00 Neptune Gear Spindle however was not there. For some reason I have a .9 Neptune Spindle in the list. I am really not sure which one is correct at this point. It's been a while. I created an stl. file of the 1.00 version and tried to attach it but Instructables will not let me save this project once I add it. I am getting an error message. I will keep trying. It will show up where the 3D parts are in the Instructions. Sorry for the missing part. I also am not seeing the .9 Gear Spindle or the .5 Frame Spacer in the zip file. Perhaps there is a problem with their filenames starting with a period? That's generally a no-no, at least on OS X... Confirmed - when I open the zip file on a Windows machine, the files that start with a period are there, but I don't see them at all on my Mac. I recommend renaming them "0.9" and "0.5" instead. Files that start with a period are considered hidden files, so they are probably on your computer but you can't see them. I'm not a Mac user but you likely have an option to View Hidden Files somewhere in your file manager. Hi David Per your recommendation I re-named 3 files that originally started with a "." . They were added separately in the parts section. I hope these work out for you ok.
8 Planet Motorized Orrery - 3D Printed: Page 22 I am also not seeing Saturn driver gear top and bottom spacers. Now, I did find the Saturn driven gear top and bottom spacers. But not the driver. I don't understand how the zip has them for you but not for me! I will use Neptune's since Darren says they're the same. Thanks Darren. And of course, thanks Widgetwizard for this awesome project! Hi Joseph Were you able to get the revised files ok? I did rename them. Sorry for the delay Joseph. See reply to David. Sorry for the troubles.
Hi Darren. Were you able to get the uploaded parts? I did rename them.
Thanks for a great project. I realize this project is 3 years old, but is it possible to have you upload a version of the orrery dial in English with the months and Zodiac in counter-clockwise order which I understand would be correct if viewed from above? This is a very wonderful project to make...…thank you Widgetwizard. I did need to correct some of my 3D-prints (especially the earth-moon-gears: they did not wanted to turn very well without blocking...…). I did print some tiles a second time in another way (slower) and then it was better. The planets were printed out in two pieces, and then glued together. I could not properly print the lower side, when it was printed in one piece.
I'm curious to know how to modified the Earth/Moon gears. I also am having trouble getting them to turn without catching up. I looks like the teeth are too pointy and/or the spindles are too far apart? hi, i did sand alot all the teeths and it was better, but not away. It still does not turn smoodly....so, i did make them lose, so i can disconnect the moon/earth(no turning)....at this moment....so, maybe we must ask the maker. I did already, but he did have the same problems, altough in the video it turns good....so, for this moment.....still not smoothly...lol....it is better with sanding but...... grts Guido Great job Guido! I am glad it worked out for you. I also had to work on the moon gears a little also. I should have tweaked the design a little to improve them. Thanks for sharing your pic! The 'bras tube cut lenght' for 'uranus' on the picture says : 3 7/8" , and on the printout-paper it says : 4 7/8" ; i think it should be : 3 7/8 " for the correct lenght. Am i right please? i did print all the parts and i am assembling the module...... mmmm.....it is so fun to do this....soon i place a picture from my system... I came to the same conclusion.
;-) in the meantime, i did place a "make" here above...lol...... just the earth and moon does sometime block..but all over it is such a nice and learning project to make. My grandkids know now almost all the names of the planets...lol...... That is great Guido I am glad you liked the project. I was quite a bit of work to design it but it was fun. Where can i find "the Jupiter Ring"-file please? ("SaturnRing-file") (is it not the 'Saturn-ring-file' instead of the 'Jupiter-ring-file?) (i am still printing but in the meantime i can make 'the Jupiter ring' (Saturn-ring?) and 'the calendar'...) grts...Guido
8 Planet Motorized Orrery - 3D Printed: Page 23 ok, i did find the answer : i have to make it myself...lol....i did find your answer : " I have attached the stl file for the Earth Ring Bottom Spacer. I cannot find the Jupiter Ring in my files. It was just a donut shape that fit snugly around the planet. It was printed on a regular printer, laminated and cut out. It really wasn't anything fancy. Sorry I did not have it. "
And you are right : it is easy to make...... sorry for my question..... i have started this beautiful project...... it is WOW...... I have already...lol...... one question : i have started printing out in 3d the first part 'Frame 1 drive side.stl' (1084kB)(twice, but that is not nescessary, i think? One print is enough, yes?). But now i see that there is also ' Frame 1 driven side.stl ' (1599kB). So i must print out also this part once? And so for the others (frame 2-3-4)? Each one must be printed out once? Sorry for my question...is this correct? Thanks...... Hello Guido There are 4 separate frame levels. Each frame level has 2 halves. If I remember correctly the quantity is 1 of each as you mentioned. I believe there is a drive side and a driven side for each frame level. Good luck with your build and I hope you enjoy it! Thank you mr Widgetwizard for answering my question....fingers cross they say.....lol....soon i hope to show you some pictures..... :-) bonjours existe te il vértion anglaise du cadran janvier février Mars Avril Juillet Juillet Août Septembre Octobre Novembre Décembre Capricorne Verseau Poissons Bélier Taureau Gémeaux Cancer Lion Vierge Balance Scorpion Sagittaire Capricorne
I ended up Integrating a speed controller to make it rotate slower or faster but amazed with this awesome model
Great! Please, any new improvments in the project? Thank you, Paulo - Brazil
Aweasome work! I'm beginning to print all stuff and in the mean time I'd ask you (may I dare?) to translate in Italian the dial annotations, like: GENNAIO FEBBRAIO MARZO APRILE MAGGIO GIUGNO LUGLIO AGOSTO SETTEMBRE OTTOBRE NOVEMBRE DICEMBRE and SAGITTARIO CAPRICORNO ACQUARIO PESCI ARIETE TORO GEMELLI CANCRO LEONE VERGINE BILANCIA SCORPIONE. I wasn't able to find any program to modify your image... TIA Hello Francesco I have attached an Italian version of the dial in both pdf and dwg format. I hope I did this correctly. Forgive me if I misspelled something. I attached the dwg file also so you can edit it in a cad program if you need to. Let me know if you got this ok because I am getting an error message when I try to save this project after they were uploaded. Hi, in effect I can't find it nowhere... Some time may happen; with thingiverse too I had little problems. Can you make it downloadable from othes sites?
8 Planet Motorized Orrery - 3D Printed: Page 24 TIA Hello Francesco. Instructables fixed the problem and I have loaded the files you requested. One of these is a cad file that you can edit if you like. Sorry for thew long delay. Thank you very much!
Hello I believe I still have the original cad file of this dial. If I do I will try to create one for you. I believe I have that at work. I can only find the pdf version at home. I will get back to you. Thanks a lot... are the planets to scale and are they a correct distance from the sun in whatever measurement was used?
Doing a science project with my son and need to know the exact distances from the son for a good grade. Hello evandn The focus of this project was the orbital relationship between the planets around the Sun in Earth years. The distance between the planets has been condensed to keep the overall size as small as possible. At the beginning of the instructions I show what the orbit times are for each planet in years. When the Earth rotates once around the Sun that of course is one year. The other planets orbit times are relative to that. Hope this helps and good luck! Jupiter Ring - Where can I find the file for the Jupiter Ring? Thanks
I was not able to find my file for the ring. It was just a donut shape that fit snugly around the planet. It was printed on a regular printer, laminated and cut out. Not very fancy. As I mentioned to a couple of other folks I am very sorry I missed this and did not get back to you way sooner. Hello! I'm going to build it with my students but i cannot find de Earth Ring Bottom Spacer between the .stl file. Can you help me? Thanks! Great project btw :) I have attached the stl file for the Earth Ring Bottom Spacer. I cannot find the Jupiter Ring in my files. It was just a donut shape that fit snugly around the planet. It was printed on a regular printer, laminated and cut out. It really wasn't anything special. Sorry I did not have and my sincere apologies for taking so long to see this and reply. Thank you for the nice comment! I had a lot of fun designing and building it! Wow !! What a great Idea and Design .
Thank you Hardik!
Are the planets distances from the sun to scale?
They are not to scale. To keep the orrery from becoming too massive i had to condense the distances. Justin, I have attached the orrery dial pdf. Please see my note on your FB page. If I am missed/overlooked something please let me know. Regards
