K40 Laser Focus Assist - 3mm Stock

thingiverse

This cylinder should be printed at a height of 49.3 mm. Its main function is to act as a reliable distance verification tool when adjusting the Z-Bed height for cutting 3mm sheet materials like wood and acrylic. There's a small hole in the base that can be used to check mirror 3 beam alignment. Line the bottom with aluminum tape, then punch through the hole with a sharp object. If you're able to fire directly through the hole, the beam is properly aligned.
