Simple minimalistic snap-fit case for arduino nano with USB-C connector (aliexpress clone, since official logo is nowhere to be seen).
It has button incorporated into the top lid and small window for viewing LEDs.
It can allow for safe (ESD-Protection, kinda) development of barebone arduino. If you would like to solder anything, sensors or modules, then it won't work.
I include the original FreeCAD file, so if you would like to expand it, to make place for additional parts (buttons, LEDs, displays, sensors etc), feel free to do it.
The author marked this model as their own original creation.
