I get your problem, yes. I also tried printing a bumper for my work phone in PLA a couple times before I was able to print TPU and it always took like 2 weeks until it broke. Those materials don’t like being put under pressure permanently. I didn’t try PETG, could imagine it to be a little better, even though it won’t absorb any impact if dropped.

That sounds durable, but not flexible. Am I right?

BTW… In the process of designing these there were made a few prototypes. They all are not perfect, but if someone (from Germany) wants one, here is my stock :D If you have questions on a specific one just ask. I would give them away for shipping+packaging cost.

iPhone 13 (regular):

• blue Mama Version
• big MagSafe Cutout Bumper

iPhone 13 Mini:

• slim hex back yellow
• thicker round hex cutout transparent
• rugged small hex back yellow with grip pattern

iPod Classic 5G:

• neon green case with hex back

Let me know if it fits. Would love to see a picture :)

Better donate the money to a charitable cause. I'm doing this just for fun.

Did you use TPU for the prints? If you used PLA, that really was a bad idea. With TPU my drop tests (not on purpose) were successful and the phone without damage everytime (so far)

Will this one fit your phone? If yes, I can modify it for you how you like ;)
