1/4 inch mount for 4040 alu profile sim rig

This is designed to be used with heated inserts, the size I used is 1/4“-20x12.7. But any ¼ inch insert should work, as long as it's not longer.

It's a very simple and convenient way to add a magic arm to your rig for mounting button boxes or your phone or flag lights and so on.
