This is a 3d printable mounting platform for the PXN Handbrake. My PXN Handbrake I had was an early version with a weak aluminum clamp that bent very easily. PXN has since revised the clamp to be stronger. This was designed to allow the handbrake to be bolted to the side of a rig. The two existing holes on the side are 52mm apart.

Unless the handbrake's material has been changed, the threads are very weak. I recommend using all three bolts at the forward side of the handbrake and at least one for the rear.
