About this 3D model

This part clips onto you MakerBot filament spool [1] to keep the filament in place during transport or printing. It is designed to work with the MakerBot filament spool holder [2]. The housing freely rotates around the spool as filament is removed. [1] http://store.makerbot.com/plastic.html [2] http://www.thingiverse.com/thing:7105
