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).

Bắt đầu bằng việc xem xét các thiết kế giá gắn LabStack hiện có và tài liệu tham chiếu 19-inch Mac Mini được liên kết, sau đó so sánh chúng với kích thước rack 10-inch trong issue này. Công việc được xem là hoàn tất khi đã xác định một giá gắn 1.5U in 3D có thể chứa một M4 Mac Mini và một module LabStack, đồng thời mọi tùy chọn keystone-jack đã được giải quyết.
