Universal 3D printer pen holder

Inspired by the rbreen Ender 3 pen mount, I have taken the general design and altered the back to accept cable ties so it can be strapped to any 3D printer head. It is important to have vertical travel but no side to side play once the pen is installed.

I started by trying to have a one size fits all but changed that to two, hence the two sizes here. The smaller suits a typical skinny pen, the larger suits a sharpie or colour changing pen.
