Before you print any of the parts, make sure that your printer is well calibrated in terms of extrusion factor and dimensional accuracy! There are some parts intentionally designed with a tight fit. Further, I recommend to print the large parts (especially xxxCase and xxxCover) in the same orientation relatively to each other as they will be assembled later. This can compensate dimensional errors of your printer up to some degree.

If you want to build this thing, you need these parts:
* Raspberry Pi 3B+, 4B should also fit
* official Raspberry Pi 7" touch display
* 2x [AR9271 WiFi card](https://www.aliexpress.com/item/32954949341.html)
* 2x [USB cable](https://www.aliexpress.com/item/4000285080584.html) for WiFi cards
