Raspberry Pi 3b+ Zigbee Server Case

I've built a Zigbee hub for my Home Assistant system. I wanted it to be distant from where my Home Assistant host is, ethernet connected and I had a spare unused Raspberry Pi 3b+... What best to use it to build it!
So I designed this case to be something nice to see on my cabinet, my wife must see it daily without having the instinct to put it in the trash bin... ;)

Materials you need to build it:
* 1 x [Raspberry Pi 3b+](https://cutt.ly/9EqcqtB) or older (not compatible with Pi4, sorry)
* 1 x [Zigbee PiHat by Giovanni Castania](https://www.tindie.com/products/GiovanniCas/zigbee-hat-with-cc2538-for-raspberry/)
* 4 x [Threaded inserts M2.5](https://cutt.ly/LEqxFBg) for Raspberry
* 4 x [Threaded inserts M3](https://cutt.ly/EEqxC6T) for the cover
* 4 x [6mm M2.5 spacer](https://cutt.ly/UEqxMPm)
