I needed a bracket/clip to hold a Switch-Pro (don't ask) to my visor. I produced a fully parametric design in Fusion. It's dimensions can be changed to create most any-sized bracket/clip for supporting relatively light objects. 

Changeable parameters are:

• Bracket length, width, and thickness
• Loop size
• Hole size and location
• Hole count and spacing 

The two things that cannot be changed are (1) removing the bottom loop (It can be removed/cut in the slicer.) and (2) changing the loop's profile.
