The two people with a jolla handset will now have to go and spend $2000 on a decent 3D printer to make their own $free case ..../s
They'll probably break though. Great idea, but those materials that are used for 3D printing aren't meant to be used on something you pick up and throw around all day.
You mean for the cheap ones. Medicine is one of the top applications, for example. There are some that even print in titanium ($$$$$$).
How much would it cost in TOTAL to print a case in titanium though? I mean, that guy had to haggle to get him to print that case for $75.
