Description
This case was designed for a DIY smart doorbell prototype, containing a Rasberry Pi 5, USB mic, USB speaker, Pi Camera 3, Button, LED, Pi power adapter + 90degree dongle.

The tutorial and 3D design were developed by media artist Roos Groothuizen and Tkkrlab hackerspace founder Dave Borghuis.
Note: The hole for the LED in the lid is located differently in every design so it's excluded from the .stl file. You'll need to add a 7mm hole in the slicer or drill it after printing. Manually add this in PrusaSlicer by right-clicking the object -> add negative volume -> cylinder.
Note: This is still a prototype. It's not fully weather-proof.
The objects in the pictures were printed on a Prusa MK3S with a 0.8 nozzle in 0.4mm layer height, with concentric bottom layer lines.
I used the trick described below to combine the graphic with the case.
If you don't own a multi-material printer like me, you can follow these tricks:
In the .3mf files, both the graphic and case lid are aligned with each other. I prepared the files in PrusaSlicer and it doesn't seem to work in Cura.
You need to export both the graphic and the lid as separate gcode files.
Decide on your layer height first.
Adjust the z-size of the Graphic to match your layer height (with the padlock unlocked)
To export the graphic, right-click on the eye of the Doorbell-Lid layer to hide the lid.
Slice the graphic and export the gcode.
Do the same thing with the lid but hide the graphic instead.
On your printer, print your graphic first.
When the print is finished, do not move the plate. Just swap out your filament and start the print for the lid. It will print right on top.
