This is a tool that can be used to focus Comgrow Z1 laser engravers. There are two versions for 5W and 10W lasers, with 23mm and 45mm lights. The OpenSCAD file can be adjusted to create other heights.

Tools are provided for 45mm, 23mm and 7mm heights.

Also provided two tools that provide three heights: 45-43-41 and 18-16-14.

This also has a holder that will clip onto the frame of the Comgrow Laser Engraver.

You set this on top of the material you want to engraver/cut to insure that the laser has the proper distance above the material.
