I was looking for a phone case for the N200 and this was the only good design, but it was for PLA and printed in two pieces. I wanted to print it in TPU so I connected both pieces into a single print and added some features. You can one-shot this print and it comes out great!
Settings:
Printed in TPU at 0.2 layer height with some supports, and it fits well. (Would probably recommend at least a 0.16 height, I just wanted to print this quickly and make sure all the measurements were good.) Not sure if this would work with PLA, but I guess you could give it a try.
P.S - I'm new at modeling, so this was my best attempt, I think it came out good.
Enjoy!
The author remixed this model.
I combined both pieces into one piece for easy TPU printing. I also connected both halves on the top for better rigidity and added a hole for the headphone jack which was not on the original.
