Phone case for Xiaomi Mi A1 (model used: MDG2).
I printed with PLA and 0.6mm Nozzle and no supports. Should work with 0.4mm as well.
It snaps right on. Fits tight. It is a little hard to get off. Which is good I think.
There are two variations. One with an open back which is a little more flexible and prints a lot faster. The other is with a closed back and should provide better protection for the phone.
I will try printing in PETG next.
Edit: PETG definitely works a lot better as a phone case.
