About this 3D model
This is a 5.25" front panel to power up your RepRap through your PC's PSU. I made it based on Thermaltake's full tower, but needs some cutting to fit nicely. Pretty messy/draft code, but the snapfit molex holder works well. It has slots to fit the 4-pin ATX Molex that is used to power peripherals. NOTE: RAMPS 1.4 is rated at 5A @ 12V without HPB, and plus 11A @ 12V with HPB. Be sure your PSU has enough Wattage to power both your PC and your printer. Also you should use 2 different molex pins to power your heatbed, as the cables get hot at those current. NOTE 2: I'm not sure what a shortcircuit on printer's electronics may cause to the PC. The PSU is supposed to shut down in that case but don't know if this will affect the PC.
