Locking Through-hole Pins

To go with my 3D printed collars for exhaust hose on my Ortur LaserMaster laser engraver, these locking pins are quick and easy to attach and remove. They fit perfectly into my collars and the lock slips on to hold together the collar and the material I'm attaching it to.

I've included the source Fusion file if you want to change dimensions, as I haven't yet jumped into making my designs customizable.
