About this 3D model

Clips a 10mm rod on to a square 22mm frame. Used with an old printer head guide rod and a steel frame fireplace wood bin to form the hub & frame of my filament spools with http://www.thingiverse.com/thing:4337. Includes a slot & fitting "U" spring clip to keep the rod in place on one end, since the rod was nicely slotted like that.
