Is there a 3D printable enclosure for RPi 4 w/ serial gateway?
I'm just getting started w/ my setup (components are in the mail), so sorry if I've missed something - I swear I've been looking.
I can't find a 3D printable enclosure to house both my Raspberry Pi 4 and my serial gateway (Arduino Nano and NRF24L01+PA+LNA). Is there one out there, or am I going to get to design one myself?
I had thought this would be a common setup, but maybe I'm over complicating things? I'm planning to run Domoticz and I read it's easiest w/ a separate serial gateway, vs integrating the radio into the GPIO pins.

I couldn't find one, so I designed my own.
(My model is not suitable for anyone else because I made it fit very snugly around my board)
Wanting a smaller, neater solution than that, I bought a nRF52840 USB stick, hoping I could use that because it's very nice, but unfortunately there are some compatibility issues I have to yet resolve.
I'm slowly working out a case design in Tinkercad.
Does anyone know if it's OK to put the NRF module close and parallel as the RPi?
Still on the journey...
Finished a v0.2 notes:
- Now have a printed case! See pics below.
- The Radio and the Arduino needed to have the header pins soldered upside down.
- The NRF24L01+PA+LNA doesn't come that way, so I had to de/re solder the pins. Not the simplest.
- The fan screws get in the way of the serial gateway assembly.
Ideas for gen v0.3:
- Turn Arduino and Radio 90 degrees , basically make a sandwich. I think there is enough room if I use a double sided perf board.
- I'd need smaller 3mm LEDs instead of the 5mm one's I've got... I've got some on order.
- Also want a fresh radio module, if I don't have to flip the pins it would be easier for anyone else to do it.
- Alignment pins - the Magnets do a good job, but little gaps are not ideal.
Again for anyone interested here's the updated tinker cad link: https://www.tinkercad.com/things/3NuVSR723k2

Looks very nice and professional!
Couldn't help but wonder however if there is a way to connect the Arduino to the RPi through internal GPIO pins, in order to eliminate the external USB cable? I think that would be the finishing touch on such an otherwise nice looking project.
Version 0.3 perhaps? If not I (and perhaps others coming by later) suppose I was wondering if there was some technical reason why not to do this?
Or maybe you simply didn't get around to it yet (perfectly acceptable reason as well ).

Designed by your own?
