About this 3D model

The starter is a lot in use for RC cars so version one broke after a while and the shaft just spinned around so in version two I added two screws to tighten the shaft. Needs 2pcs M3 nuts and 2pcs M3x12 hex screws. If your shaft is bigger than the design allows just drill it out a little bit and tighten the screws and it should still clamp.
