Bobby Car Trailer Pin

thingiverse

Hi, first upload to this great community. If you're like me and bought the Bobby Car and the trailer separately from second hand you're most likely missing the trailer pin to secure it to the car. I did a quick octagon version. No supports needed and print in place. The bearings are in a conical shape to ensure easy printing. 0.4mm clearance between moving parts (2x layer height) to ensure free spinning. If you're having issues with first layer adhesion I'd recommend using a brim since the front parts first layers are quiet small. For heavy kids use I'd recommend 50% infill. If it's used outside a lot probably PETG is the better choice of material. Have fun with it.
