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!
Check these resources to help you with your tractor build and don’t forget to share pictures of your tractor.
- 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!!

Here is my TEA20, builded during the development with Cristobal. What a great project, it was a real pleasure to discuss about this one with Cristobal. He's a great designer, the goal was to be more realistic and makeable possible, and the challenge is grandly achieved ! Thank you my friend for this awesome tractor and to make my dream come true !
