Motorcycle swivel cup holder

I based my design on dbostian's original design (great job btw). From there beefed it up for more rugged riding and left enough space on clamp-downs for a thin piece of rubber to prevent slippage and scratching. It fits 1'' bars perfectly. Resize to your desired measurements as needed (this one accepts large from TH and McD's). Keep in mind that that will also change hole sizes for mounting bolts and nuts. I designed it to use M4 35mm bolts and locknuts all the way around (5 sets total). Yo
