Double 32mm x 57mm filament hub

This filament bushing works with 32 mm and 57 mm filament spools. It houses a common 608Z bearing.

I printed it at .3mm layer height, 2 perimeters, 3 top layers, and 15% infill. It takes about 30 minutes to print with these settings in Slic3r.

Let me know what you guys think as this is my first of many contributions to Thingiverse.
