Add M4 Mac Mini 1.5U Mount with 1x LabStack Module

@GarnetSunset single or dual M4 Mac Mini 10inch rack would be amazing, probably 3D printed to save on cost!
myelectronics.nl has already showcase it's possible for 19" rack > Link

For a 3D printed mount, it would end up being closer to 1.5U rather than the 1.25U of that mount, just to make sure there's enough material for the weight of the Mac Mini, and for a 10" rack, you wouldn't be able to get more than one Mac Mini.

The total opening width on the 10" rack is ~222mm (8.75"), and each M4 Mac Mini is 127mm (https://www.apple.com/mac-mini/specs/).

Thinking out loud, I could probably make a 1.5U mount for the M4 Mac Mini, plus a single LabStack module on its side, and MAYBE a keystone jack for the MacMini's Ethernet port and/or HDMI port. I could DEFINITELY make a 2U version, but would still only be able to add a single LabStack module, but it would allow multiple keystone jacks for the Mac Mini...

Let me know if there's interest, and I'll see about adding it to my list for LabStack modules (so long as Jeff doesn't mind the hijack).

先檢視現有的 LabStack 安裝架設計以及連結的 19-inch Mac Mini 參考設計，然後將其與此 issue 中的 10-inch 機架尺寸進行比較。完成的標準是定義一個 1.5U 3D 列印安裝架，可容納一台 M4 Mac Mini 和一個 LabStack 模組，並解決所有 keystone-jack 選項。
