Tripod 35mm base to 17mm ball for phone/tablet holder

Simple adapter to mount your phone to a tripod. Fits tripod with a 35mm x 35mm x 8mm base. The 17mm ball fits most phone holders.

OpenSCAD file is pretty simple, but requires BOSL2 library installed (which you should already have if you're using OpenSCAD!). It should be pretty easy to adapt to other tripod sizes.
