About this 3D model

Modifications and add-ons for PrintrBot Simple V2. All items designed at 3dtin.com and I couldn't figure out what the heck their units were doing, so everything needs to be printed at 0.7 scale - sorry! Edit: Added a second revision of the flanged cap. Depending on your reel, this one might fit better (slightly longer). Edit: See new spool support parts at http://www.thingiverse.com/thing:149928
