7/17/19 - Updated to use Customizer to allow changing the width for different visor thickness.
On a recent trip I was wishing I had a way to mount my switch to the sun visor. There are a few really good designs on Thingiverse, but I wanted something with no straps or gluing. I don't have much road time using these yet, but they seem to work pretty well. Feedback is welcome.
I printed at 100% infill to get more strength, but they seemed ok at lower percentages. The OpenSCAD source is included.
