About this model

This is a phone case for the popular “dumb phone” QIN F25. It sits very tight around the phone, my daughter has been using this for a while and she is happy with it (and that is all that counts).  You can print this in any material that you like, I have done so in PLA and PETG so far - will also try TPU once my next filament shipment has arrived. I suggest you use a separate support filament for the support interface to assure the cutouts come out nice and smooth. Tolerance is 0.15mm all around, which means you will have to use very gentle force to get the phone in. If your print comes out any different than very snug, it is probably because of your settings or the filament that you used.
