The file 'Printrbot Simple Metal Filament Cradle V2.0 3D Printer Model' is (skp,stl) file type, size is 1.3MB.
Updated to hike up the shafts going down to allow full Z travel, and shortened the "wheel base" to allow it to hold smaller spools, such as nylon. Also prints as a single piece (not including the wheels)). Also made it able to hold narrower spools.
Thing to hold a variety of filament spools on top of a Printrbot Simple Metal. Designed to hold the spool clear of the full travel of the Z axis, with a minimal mechanism. The spool might spin OK w/o the bearings, but, hey, why not ?
Uses 4 planetary bearing (http://www.thingiverse.com/thing:497136).
Built and in use on my machine.
