This is a Raspberry Pi mount for the original Prusa MK3S+ that works with heat sink type cases, such as the Sertronics Armor case or the Joi-It Armor Case or any other case of this type. It works with Raspberry Pi 3 and 4. You just have to have the right case respectively.

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.
