150 g class Combat Robot

This is my design for a vertical spinner bot. The chassis and wheels are meant to be 3d printed, the spinner machined from tool steel or some other high-strength material, shaft from mild steel, the rest is meant to be cut out of sheets of polycarbonate. Uses o-rings for tires and small bearings in the spinner. These are readily available in most hardware stores. Wheels and pulley drive holes are sized for basic n10 motors. Holes in poly-carb plates are for screw-and-couplers to hold the whole thing together. Suggest using lock-tight. Let me know if you had any luck with this design by leavind a make. Feel free to leave a comment if you have questions or need further specifications. I'll try to get back to you ASAP. Thanks!
