Printrbot Wooden Spool Hubs

I have some awesome spools of filament from Printrbot and wanted a hub to use with bearings. This thing is that thing.

This is an early work. Of the get go I see it could be a little over built in areas and under built in others.

Update: The *mk2_fixed.stl file was ran through cloud.netfab.com to fix it since slic3r was previewing it weird.
