Adjustable Laser Pointer Rod Holder

thingiverse

I needed a way to attach a laser pointer to a rod and make precise adjustments. I combined three parts from other makers, making some modifications along the way. Since I didn't have a short rod to hold the end of the springs, I adapted the slot to fit a #3 machine screw. The inserts for the side of the mount that moves are brass eyelets with a 1/4 inch shaft. You might also search for brass grommets. Check your local craft store, as they may have them in the jewelry or leather-working section. Adjustment screws measure 1.5" and are 6-32 threaded. The rod mount screw is 3" long and 3/8-24 threaded. Other parts were purchased at Menards, with packaging showing size specifications in photos. This device was designed using Tinkercad.
