About this 3D model
This is 3D printed bracket for an inexpensive light-bulb socket (see part list). The snaps and dimensions are compatible with the other objects I've tagged with "Elements" This thing is intended for use in a truncated-icosahedral lamp, once I find some affordable low wattage CFLs. I designed the part by minor modification to the circular elements OpenSCAD script : http://www.thingiverse.com/thing:5859.
