Customizable Camera Arm (Extrusion Mount)

Main post is located at https://www.thingiverse.com/thing:3317860

This is a customizable camera mount that can support M3 through M6 sized screws and adjustments can be made to improve fix and motion of arms.

The default settings are for M3 screws. Everything fits well, but note that the nut capture is intentionally very tight so that tightening the screw will pull the nut in to the slot. Adjust the allowances if you have difficulty getting the nut to sink in to the slot.

Note that the screw size adjustments don't affect the extrusion screw sizes since I believe M3 is the largest that will fit the 20x20 extrusion this was designed for.
