This is a pin for the glowforge laser bed. I use these to align materials while allowing them to be lifted and replaced.

Because the holes in the bed are irregular and a tight fit is important for alignment, these will only fit in limited spots. I expect you may want to tweak the sizing for your use case.

You need to print in vase/spiral mode or they will have no shear strength and be almost useless.

The provided gcode is for a monoprice mini delta.
