What sucks (or is awesome) is that if this gets popular, it will certainly show up on Alibaba in the next few weeks and Amazon a few weeks after that.

It will be a nicer material while much cheaper too.

The material thing is debatable. 3D printed Polyamide - possibly with a fibre filler - is really nice for phone cases, in my opinion. The surface texture is grippy, it's quite durable (and I like the look).

There are already charging cases that is a little thicker, that offers usb c input.
