This is a cover to fit the power supply used with the Bukobot 3D printer. I had an old computer power supply and removed the power entry module and power switch and rewired it to use here. I'm including the Autodesk Inventor files I used. 
Issues: The power supply only has one mounting screw on one side available for attaching it so it wobbles a little; I had splitting problems when I made the first one, so I made it thicker and added thickening in areas which helped quite a bit. 
There is a version without components and another for different components, the pdf showing the size of the cutouts.
