What a great design. Thanks!
Can you tell me what the minimum and maximum diameter laser can be used with this?

Good Job !


Nice design. Did you have to buy the install tool for 4-40 threaded inserts? It's very expensive.

Thank you for checking out my design! I did not use the tool that McMaster sells, when installing these in plastic is is unnecessary. The easiest way to install them is to get a socket head cap screw about the same length and hand screw it all the way into the insert. Then use a hex head screwdriver (make sure it is straight, and not a ball head) and screw the insert into the plastic using the driver. Once the insert is in far enough, you should be able to easily back out and remove the cap screw.
