ATX PSU Bench Supply

thingiverse

This is my custom-built ATX PSU Bench Supply. Each side of the casing is printed separately as individual parts, then assembled together to simplify cable management and reduce support during printing. Minimal support was required, but usually just a small amount for each part. I used 0.2mm settings for all parts, however, I reduced it to 0.1mm for detailed knurled thumb screws and 0.15mm for the small voltage panels to ensure clear text printing. In addition to the 3D printed components, I utilized: - A few dozen M1-M3.5 nuts, brass inserts, and bolts - Also sixteen M3.5 buts/bolts for the terminal blocks (and sixteen small bolts that came with them for the half connected to the PSU) - Eight twenty-amp toggle switches - Sixteen fifteen-amp terminal blocks for connecting wires - A single-pole rocker switch for power - A five-watt ten-ohm resistor to trick the PSU into turning on - A smaller 0.25-watt three-hundred-thirty-ohm resistor for the Pwr_OK LED I printed each part lying down on its flat side, and I've included a full STL of the final assembly in case you need assistance with assembly.
