here is a whole kit to take your power supply and finish it off. models for each end cap, the rubber cushion feet and a strain relief for the cord going to the printer. read instructions for some tips. the ones in the pic were printed in esun petg and painted.the strain relief and feet are printed in ninjaflex. print the feet with 2 perimeters and 15% infill. it makes them squishy for shock absorption and not too hard. the strain relief can be printed solid. its designed to flex just enough when printed solid. the psu shown is a meanwell 400 watt. i think the dimensions are the same for the 360 and 450 but double check that. the rubber feet are attached with some 3m automotive double sided tape this is the power cord: http://www.newark.com/volex/vl-0136-14-200k/power-cord-nema5-15p-iec-2m-15a/dp/46M3028?ost=46M3028 and the switch: http://www.newark.com/cherry/cre22f4bbbne/switch-rocker-spst-20a-250v-black/dp/01M7235?ost=01M7235
