About this 3D model
This is a cover for this power supply, and many very similar ones http://www.ebay.com/itm/150946378624?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 It is a modification of the RepRapPro cover to fit this particular power supply. Aside from the different cover size, the DC and mains sides are reversed, and a different mounting system is used because of a different screw hole configuration. Additionally, the DC cable hole is larger so that thicker cables can fit.
