Summary

here is my printed front plate with a 20 amp meter and radioshack jacks. the jacks are the double ones at .750 inch center to center. the face plate itself can be removed to wire it or fix it. basic shape of the printed parts requires no drilling to the ATX unit, or other modifications to the sheet metal. the face plate extension is big and mine curled a little on the print bed, but this has little effect on the front plate. the back plate will be modified for more strength later, and updated here. you can also use the face plate as a panel mount. i also give you the blender files so you can design your own parts directly from it.

NOTE, the back part works just fine, put nuts and washers on both side and the the back part will be straight
NOTE, handle is done, will upload asap

the sheet metal box of the atx is 3 7/16 x 6 inches
