Raspberry Pi Zero USB Dongle Case

Simple 3d printing friendly Raspberry Pi Zero USB dongle case.
……………………
It was inspired by idea of converting Raspberry Pi Zero to USB dongle: https://www.raspberrypi.org/magpi/stick-pc-pi-zero/

Case has bevelled edges so it does not require any post processing and it is pleasant to hold.
It is screwed together using 4 screws. I prefer screws over "clicking" because they work reliably and allow repeated assembly and disassembly.
I recommend using Plastite #2-28 x 3/8 screws to hold it together: https://www.amazon.com/gp/product/B00GDXU8AA
You will also need standard USB A male connector. I got them in this nice set: https://www.amazon.com/gp/product/B072M6SJL8
If you want to see LED blinking, drill (1.8mm or #50 drill bit) or pierce thin cover of the pre-made filament guide in the top of the case and insert short piece of translucent filament as light guide.
……………………
Case is designed in OpenSCAD for extrusion width 0.5 mm and layer height 0.2 mm, which delivers 4 perimeter walls and strongest case. Infill 100% is recommended, no supports required. Tested with PLA and PETG.

Note: From some reason Thingiverse does not render SCAD file properly. It works as expected in OpenSCAD though.
