About this 3D model

This is a derivative of http://www.thingiverse.com/thing:13626 and http://www.thingiverse.com/thing:13192 but I can't mark it such currently. This nut has a FreeCAD source file which allows for parametric configuration of number of holes, hole spacing, nut width, etc. It is part of the MendelMax redesign, and the latest official version will live at https://github.com/maxbots/MendelMax/blob/master/partsrc/TSlotNut.py
