Spool Bushing

Here is a revised spool bushing based on my previous http://www.thingiverse.com/thing:753630. This version can be be customized in the customizer. Any parameter can be changed making this suitable for any spool on any rod that will fit.

The original Description below:

This is a spacer for http://www.thingiverse.com/thing:705345. Print 2 and put one in either side of the spool. It acts as a bushing and gains a little more clearance between the spool and printer. It also prevents the spool from cocking to one side or another.

Over all it just makes it easier on the extruder and satisfies OCD.
