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.Don't print it with TPU its not preferrable. This design is inspired by https://makerworld.com/en/@diego99rrThe design was not available for my iPhone 12 mini model therefore i made my own from scratch.
