Summary

NOTICE: Use extreme caution when working around high voltage and high current devices! Please seek assistance if you are not comfortable working with power supplies.

Update 12/09/21 - Increased overall length by 10mm to allow more space for wiring.

Update 11/14/21 - Added the embossed labels back that were eliminated in a previous update.

Update 11/04/21 - Added key slots on both sides of the power switch opening so that switch can be mounted in either orientation. Included link for round switch.

Update 10/25/21 - Recessed the fuse holders a little more to allow more exposed threads on the back side and modified the round holes so the fuse holders are captured in place. Modified the vent slots on the right side so they are less likely to cause problems during print.

I really liked the compact ATX benchtop PS by gdoniu93 and started out simply to recreate the model in Fusion360. Somewhere along the way (as it often happens with me), I decided to totally redraw the original design to better accommodate some minor changes that I decided to incorporate. These changes include:

  1. Change front panel thickness from 7mm to 8mm so that brass inserts could be added.
  2. Enlarged the front panel mounting holes to accommodate M3 brass inserts.
  3. Replaced the rectangular On/Off switch with a lighted round switch (only because that's what I had on-hand)
  4. Added fuses for all output voltages.
  5. Removed the grill work on the right side simply to reduce print time a little.
  6. Added embossed text for output terminals.
  7. Recessed the variable output terminals the same as other output terminals.

I am printing this remix now and will post more pics when it is assembled and tested.
