Gaui X3 boom clamp to prevent boom slipping

A 15mm clamp to stop the boom from slipping into the body and the belt becoming loose.

Use a M2 locking nut.

This is best printed in PETG (or ABS) because they are stronger than PLA.

However, PLA also words well but cannot be tightened as much because PLA will split.

Print with plenty of infill, I use 50%.

EDIT: V2 is a bit stronger and a bit tighter on the boom as I was having trouble tightening this enough.
