A pen holder for a ORTUR 150x150mm laser cutter. It is mounted where the laser originally is. It is used to hold a pen in place so that you can use the laser cutter as a plotting device. This is part of a larger project on my GitHub: https://github.com/Papas12213/Voice-Script/tree/main 

The holder features 3 screw holes, the top 2 screw holes are used to mount the holder, and the side screw hole is used to tighten and keep the pen in its place. The holder also features a hole in the middle that is used to align the holder in the center of the head. It also has a small cutout in the back to account for the belt.
