Rat Racer

thingiverse

Transform your rat trap into a speedy vehicle with these accessories: print two end caps, axles, and pairs of wheels. Ensure you have a Victor brand rat trap; adjust OpenSCAD source files for other dimensions. Remove the cheese platform and retainers from the base, leaving the spring-loaded U bar. Attach end caps, insert axles through them, add wheels, string to the U-bar, thread it through the axle hole, wind around the axle, place on floor, and rapidly release the U-bar for a spinning car in theory; practice reveals success may vary.
