Iphone 12 Mini Exoskeleton Case

Here's the first case I've designed. It covers only the corners, allowing the body of the iPhone 12 Mini to remain highly visible.

I have Printed it with PLA but PETG would be a better option. 
Printed it with 3 wall at 0.2mm layer height but for finer professional look print it at 0.08mm layer Height.

This design is inspired by https://makerworld.com/en/@diego99rr

The design was not available for my iPhone 12 mini model therefore i made my own from scratch.
