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](https://www.myelectronics.nl/us/19-inch-125u-rack-mount-for-3x-mac-mini-2024.html)

> 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).

Commencez par examiner les conceptions de supports LabStack existantes et la référence liée du 19-inch Mac Mini, puis comparez-les aux dimensions du rack de 10-inch indiquées dans cette issue. Le travail sera considéré comme terminé lorsqu’un support défini de 1.5U imprimé en 3D pourra accueillir un M4 Mac Mini et un module LabStack, avec toutes les options de keystone-jack résolues.
