I'm totally new to the 3D printers world and I am actually running a phone cases business. Until now, we were buying our cases from China but we were wondering if we could 3D print our own phone cases to sell them after. So my questions are the following :- Is it possible to build blank phone cases with a 3D printer for any phone brands ?- What would approximately be the cost for one phone case ?- Will the cases perfectly fit the phones they will be created for ?- What would be the cost for a "good" 3D printer for this purpose ?
