How to edit you own custom sized handle bar mount:

this is a mount for a camera on a 28.5mm handlebar. thats the normal thick part in the middle of a dirtbike handlebar. you could mod the size to any pole diameter also, this design works really well with only one clamping screw. the hardware is m5 bolts and nuts. 

Im using it for a second camera view for motorbike vids
