This is a trailer for the OpenRC tractor. You can use two micro servos to control the rear ramps.
Print all parts (the rims are the same as the OpenRC tractor)
Assemble (it's quite easy)
Fix cables with cable clips
Get your tractor and ENJOY!
Feel free to ask any questions about assembly or other doubts.
Practicing to park with the tractor is really challenging and fun!!
