Armor Case Raspberry Pi Mount for Original Prusa MK3S+ Frame

If you use a Bear frame check out the Bear version of this mount.

Updates

V2 - 2024-03-25: New version with a hook at the top for more stability against material creep or pulling on the power cable. Both versions are totally fine to use.
