I discovered the "Laser Offset" in LightBurn which prompted me to build this mount for a 12mm laser module. It glues to the corner of the laser head and allows for alignment of vertical lines for squaring (once calibrated) and the cross in the center when the Laser Offset is dialed in makes a great tool from the "Current Position" job origin in LightBurn.

The biggest problem with these small 6mm and 12mm laser modules at that short distance is they are too bright and bloom. Inserting a 47-ohm resistor in series with the battery supply was just the fix. I'll put the links to all the bits-n-pieces below.

UPDATE: The little CR2032 battery was just too weak and didn't last long. I upgraded to a small dual AA cell battery pack. Will update pictures when I get it mounted.

Resistor: Pick up any cheap multi-pack. 47ohm is common and should be in most. The smallest quantity I could find online was https://www.amazon.com/Projects-10EP51247R0-Ohm-Resistors-Pack/dp/B0185FJZG6

Screw:
You're on your own. It is a tight enough fit that I had to take the sticker off the laser, so it isn't really needed but I wanted to take the time to align it and secure it. I just used something from my random screw jar. You can ream it out some if needed. The hole was 3mm
