I printed the case made by Tig3rch3n, but I thought there was room for improvement, so I re-made it.

It is also snap fit, and the holes should be a little more aligned.

You can print it with an infill pattern (and no top and bottom layer) if you want :)

I think my printer is nearly calibrated, but maybe you'll have to play with scaling in your slicer.

I just tried in PLA, and I'm printed right now a TPU version :) (aaaaand... the tpu version is too loose... :( )

Let me know if it's working for you :)
And last note, I designed it in Onshape, I don't know how I can share the initial design.
