USB-C Portable Adjustable PSU DSP5005 - 100% Print in Place

Look ma, no overhangs!

I love the original model, but it was missing a few design elements which make printing a lot easier - so here's my take!

All STL files require no supports, and are pre-orientateded. Highly recommend turning on arachne path generation, if your slicer supports it. Besides the required soldering of the electrical components, everything else snaps into place with no fasteners required.

Shopping list (from original creator):

• Psu module: https://aliexpress.com/item/1005004493690896.html
• USB-C pd board: https://www.aliexpress.com/item/1005006323268960.html
• Banana plugs: https://www.aliexpress.com/item/1005005603788873.html
• Some glue/epoxy, to hold the USB-C PD board down into it's sled.

Changes:

1. Removed:
   1. 2mm brim on face, which ensures a lovely front-facing layer.
   2. “stop” lines on right and left sides (not required with new leg design)
2. Added:
   • "Point" feature to the side bolt holes.
   • Ventilation slots on the “top,” with small 2mm overhangs that are easily bridged.
   • A 45-degree slope to the “back” insert holders.
   • Ridges for the back cover to clip into place.
   • Support for a USB-C sled.
   • Enlarged banana plug socket holes from 4.2mm → 6.2mm, as the recommended sockets don't fit in the original 4.2mm holes. 
3. Completely re-designed legs:
   • Print in place.
   • Larger holes in main body to accomodate new leg “plugs/hinges"
   • Snap into position, either open or closed.
   • Curved profile matches the body’s contour, acting as a stop when fully open.
   • Snug fit when legs are closed.
   • Tolerances of 0.1–0.2mm allow slight movement but ensure compatibility with most printers.
   • Tips of the legs are cut to the correct angle for maximum contact with the countertop when in use (and unit is at an angle).
4. Back panel no longer requires inserts/fasteners
   • existing back panel model can be used, however,
   • new back panel with mounting holes and airflow slots for a generic 30mm Raspberry Pi fan on the back (inspired by this design).
   • new back panel uses existing hole pattern, if you want to continue to use heat-set inserts + screws.
   • added ridges to hold back panel in place without inserts/screws - ridges are present on three sides, just clip the short end in first, and push the rest of the panel in. Use a screwdriver or butter knife to lever-out/un-clip the back panel using the empty slot.
   • replaced overhang with 50 degree champher at back of USB-C board.
   • Thickened USB-C PD board “sled”.
     • You'll need to glue/epoxy the board down - couldn't think of an easy way to secure the board in it's tray (happy to hear any ideas!)
