first iteration of an enclosure for a Raspberry Pi 4 and a Streamdeck XL.
Please be aware, that the Ethernet and USB Ports of the Raspberry Pi 3 and 4 are placed in the opposite direction. The "real world" images were taken of an early version running on a RPi 3B - the STL files are actually for a RPi 4!

The following parts are needed:
1 Raspberry Pi to run companion on it.
1 Neutrik Ethercon D-Series connection (e.g. Neutrik NE8-FDP-B)
1 Pi HAT PoE (the one without a display!)
1 super short RJ45 Cable (ideally very flexible)
1 super short USB-A to USB-C cable
4 M3 x 8mm screws & short inserts for the Backplate
4 M3 x 10mm screws & short inserts for the Top Cover
4 M3 x 12mm screws & standard inserts for the Base Plate
4 M2.5 x 8mm screws & inserts for the Pi - (you can also use M3 - but you need to widen the wholes a bit if you're not afraid to damage your Pi :-P)

I keep the Streamdeck removable - you might want to glue in some magnets, but I find it's strong enough without. Depending on the Ethernet Cable you use … It might be VERY tight - I had to remove a bit of the protecting part at the end of the connector. Assembly is a bit fiddly in general - be patient, after you cursed the sh.... 2 or 3 times, everything's gonna be alright. :-P
