Robin Nano to BIGTREETECH SKR Mini Adapter + Raspberrry Pi Zero / 3 / 4 / without (e.g. Sapphire Pro)

Just a simple adapter to mount a BTT SKR Mini (or any other board with the same size, like the Creality 4.2.2 on the Photos) onto a Robin Nano mount.
In my case, it's designed for the Sapphire Pro, but it should fit into every other printer, which has a Robin nano mount.

The raised points are designed for the use of threaded inserts (4.6mm).

I have uploaded 3 different models:
1. only for the SKR Mini
2. for the SKR Mini + Raspberry Pi Zero or Zero 2
3. for the SKR Mini + Raspberry Pi 3 or 4

I've printed mine with PETG (13% infill, no supports)

Update 03.06.2022:
Added a more compact version of the one for the Board + Raspberry Pi Zero
