10" rack and printed panels

Hi All,
In getting ready to build the Open Hornet simpit, I thought I needed to make myself a robust power supply with a few features.
Owning a Creality K1C was a limiting factor for being able to print larger items, but I came up with this idea: 3 part plates - the 'Z' shaped ears and the main panel.
The ears mount to the rails as per normal, and step back 3mm to allow the panel to flush mount on the ears. 10mm overlap at back. M3 fasteners at same pitch as rack rails contribute to holding it together.
Generated 1RU, 2RU and 3RU ears and blanks.

If it's been done before, OK. If not, let me know, OK?

No repository files, tests, or entry points are named. Start by reviewing the existing printable rack designs and comparing them with the proposed 1RU, 2RU, and 3RU ears and blanks; the issue needs an agreed contribution scope and acceptance criteria before completion can be determined.
