OpenRC Tractor MK3 TEA20

myminifactory

The new OpenRC Tractor is finally here!! It's been almost two years since I started working on this new MK3 TEA20 project. Now, after hundreds of hours of design, test, print, redesign… it’s finally here and all the hard work has paid off! I think it turned out great and I’m very excited to see if you like it!  It has been completely designed from scratch and has many improvements over previous versions: Dual motors Much more detail and realism Much easier electronics management No differential (forget grinding problems) Ackerman style steering Standard servo 3 part wheels (beadlock style), so tires can be printed in any filament, flexible or not. My plan is to continue working on this project. I think it has endless possibilities. Sometimes, it’s difficult to find free time for this, but even if sometimes slows down, the OpenRC Tractor never stops!

List of materials and printed parts (BOM spreadsheet) Assembly video Electronics connections Considerations: Some parts have a “sacrificial layer”. It was made this way to avoid using supports. You’ll just have to remove them manually before assembling. I use the tool from the BOM spreadsheet. All parts should be correctly oriented to print the way they are (let me know if they’re not). Total printing time is around 70 hours but of course that depends on the printer/settings you use. Recommended printing setting can be found in BOM spreadsheet   Special thanks to my friend Nicolas for all the help! If you like my work, you can buy me a coffee or paypal.me so I can keep going Thank you!!
