Raspberry PI 4 SSR DIN mount
thingiverse
Adapter to mount a Raspberry PI 4 onto a standard solid state relay DIN rail adapter, readily available on Aliexpress and Amazon (search for SSR DIN rail). The spring in the typical 3D printed clips used with other PI DIN rail mounts can be fiddly and often breaks when unmounting from a DIN rail. The metal DIN rail adapter doesn't break, and also provides a much sturdier grip on the DIN rail. The biggest drawback is a 3-4mm higher installation height compared with the printed clips. The adapter does not have cutouts for 2.5mm nuts, but a STEP file is provided, and it should be easy enough to adapt.
