Pwnagotchi case for Waveshare e-ink display

I love the Pico Projects' Pwnagotchi Pi Zero e-ink Case by PicoProject, but the supplied .stl of that particular design is hard to print. Also, I could do without the Pico branding. So I remixed the STL in Tinkercard and created a new STL that is easier to print and has no branding.

Printing:
In order to get a nice finish, I chose the AMOLEN Matte Navy Blue 1.75 mm filament, that has a matte finish, a soft touch and has great physical properties. Maybe I'll give a nylon filament a try as well, but this design gives a really solid case that has no real need for flexible materials.
