Improved Assembly / Inspection Stand for AR15

This is an improved stand that fits in the AR15 magwell to support it for assembly and inspection. The dimensions are adapted for printing on the RepRap Prusa i3 class of build volumes (180mm wide x 170mm tall). The example was printed using the Monoprice Maker Select version of the Wanhao Duplicator i3. This design will support a full rifle, as shown in the photo.

I designed this part from scratch using basic magwell dimensions in FreeCAD 0.16.
