Filament Mount for Lulzbot TAZ

Inspired by others I have been trying to find a better way to feed the filament to my TAZ 4. To hold the bearings and the spool I opted for the design from http://www.thingiverse.com/thing:235925 which was also suggested by http://www.thingiverse.com/thing:773863

However, I had some trouble with that mount when feeding brittle filaments - the extra distance from the filament tube caused more frequent breaks.

So I used OnShape to design a more compact mount.

The OnShape design is public
