Moustrap Car Frame and Wheels

thingiverse

I make mousetrap cars every year with my students and this year I really wanted to print a frame and wheels with the printer. The frame is in two parts and connected through 2 small pieces of 1/4" diameter dowel The wheels are 2.5" in diameter and has the ability to accept a 2" inner diameter o ring for traction. The grooves in the wheels help give the o ring a spot to rest in. The center hole is 1/4" diameter and extends slightly past the wheel to give clearance between frame and wheel. The wheels are connected through the frame with the 1/4" dia dowel. Supports for the frame only needed in holes Supports are needed for wheels. Print hole side down and supports shouldn't be too much of an issue. Black filament was used for wheels. Blue for the frame. All PLA
