Laser Cutter Height Focusing Tool

Tool to focus the laser on a laser cutter machine.
With a hole so you can place it on the emergency stop button of almost all the Laser Cutter Machines.In case you don´t have it just make a hole with a driller and glue some magnets ,so it stays attached to the machine.

Due to different heights adjustement(depending of yours lasercutter),i have make different measures.
If you need any other just z scale up or down the 3d model on your slicer programm on your needs.
