Replacement Frame Brace for Silver or Black PSU - Prusa Mk3, Mk3S/S+, and Mk4 - 3 variations

I built the Lack enclosure designed by Prusa (https://www.prusaprinters.org/cheap-simple-3d-printer-enclosure/), and wanted to move my Power Supply outside the enclosure since I would be printing ABS.

But, the replacement frame brace didn't seem like it was enough, and was - quite frankly - boring.

I redesigned the brace with additional ribs, material removal cutouts, and re-positioned the main face to give a much stiffer result.

Plus, I think it looks cool and I got to play with some analysis tools (which is always fun).

This is a very easy print; no supports are necessary.

Edit 2023-07-03: Added additional models that should fit the Mk3S/S+ and Mk4 Delta (black) PSU frame mounting location (with 30x30 frame extrusion slot-nuts on the side).
