Inspired by: https://www.printables.com/model/1085216-ruler-stop-block

I made a customizable version of it.

I didnt bother to put a heat insert in, just cut the threads with the bolt, YMMV.

NOTE: I WOULDNT RECOMMEND THIS, MY BOLT NO LONGER TIGHTENS, DONT BE LAZY LIKE ME AND PUT A HEAT SET INSERT IN.

I also used a M3 bolt insted of M4.
