The Nunchuck gets a nice "click" when you push it in.
My display display placement was a bit crooked: both the LCD panel on the PCB and the alignment of the display PCB with the main PCB.
Because of that, there is a bit of a gab and the fitting is a bit tight. I didn't want to change the model for this, because I don't know if this misalignment is common.
The crooked LCD is also the reason why the entire mounting is done onto the base plate: the main PCB is a more reliable point of reference for the rest of the hardware.
There's only 1 mm clearance below the ESP32. This gives you very little space to connect a micro USB connector when you open the case. There are sufficiently flat connectors out there that fit, though. You could always edit the design to shift everything another 2 mm or so.
I've added the source file for FreeCAD, so you can change it as much as you like. Most layers have readable names.
Printed with a 0.4 mm nozzle (due to 1.6mm wall thickness) and 0.2 mm layer height. Different layer heights should work fine.
