Headphone Holder with Screw Tightener

Got the idea for this after seeing a metal version of it on Amazon. I had printed out the headphone holder that had the spring in it but this is more sturdy and solid. This will fit on a shelf or desktop up to 1 1/2 inches thick.

I did have problems using Simplify3d slicing the screw. It kept breaking where the screw met the handle. I did not have this problem using Cura.
