Gravity Drop Bumpers

Wanted to buy some bumpers for my Worker Talon straight mags, but didn't want to pay 5 bucks a piece. Integrated fluting on the inside and a small hole at the bottom to let air flow through, which allows them to go on easily, stay on, and be removed easily as well. Was also hoping to keep them low profile enough that they'll sit comfortably in a chest rig or bag.

Used 95A TPU to print this, but honestly these could be printed even softer than that to increase impact resistance.

These should be short enough to be compatible with the curved magazines, but I have none to test them with. Any feedback on this would be super helpful! Also considering using the design to make a mid-mag wrap as well if anyone's interested, since this was mainly for gravity drops and being generally clumsy.

And feel free to modify these however you want, I just like a little credit for the original design. And please don't sell commercially without contacting me ahead of time, the whole point was that this should be free!
