About this 3D model

This is a functional replacement for the $35 metal handle they sell for the metal simple. It even has tappable (can use a metal M3 bolt to tap) holes for mounting the easily removable spool holder that printrbot provides an stl file for. https://www.youmagine.com/designs/printrbot-simple-filament-spool-holder The spool holder is shown attached to the handle in an included photo.
