I will echo the other comments that it does look nice, however it is difficult to print cleanly. I ended up going with another case design in the end

It works really well but there is a bit of a flex on the back panel where the components are pushing on the plastic.

Okay, so the model sure looks nice. It isn't exactly the easiest print, tho.

I printed this in PETG with a 0.3 mm layer height, for speed reasons. The design has a couple of issues:
- Sliding the screen in there the connector needs to take a steep turn towards the backside, where it will connect to the display board. Making it take that turn is finicky it best. I managed to get that done with some sellotape that allowed me to pull the connector in the right direction.

- The display board is positioned in a way so that the screen connector buckle and the battery connector end up right on top of each other. Thats bad, because that takes too much vertical space and the lid doesn't fit. Please see the attached pictures. I didn't find a way to route the components differently.

- The top part of the screen doesn't clip into the case, it just lies on top of it. There isn't anything to keep it attached. So if your print is off just a wee bit, chances are the top will detach.

Obviously, if you want a cleaner look, you'll need to print this with 0.2 mm or below. But that's gonna take a while.

I'll probably print or design a different case soon, but this will do to get the initial setup of the device done.

@a2my7463_2553374 I think you did not remove all the supports where the top slides in. I made this mistake at first then after removing them there is no bowing.

Had to slow it down by a lot ot get the edges clean
