Customized version of http://www.thingiverse.com/thing:53451 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=53451 This is modified ever so slightly to fit a 1/4" threaded rod that I'm using to hold my filament, and to fit inside of both a microcenter generic brand filament spool, and an inland brand filament spool.
