k20 / k20 pro / mi 9t / mi 9t pro

thingiverse

the design is not perfect, but I have not seen anything better in thingiverse at the moment and more and more people have this device. I recommend improming on TPU or filaflex. I also recommend that you scale it to 99.5% if you want it a bit more adjusted to the device since the design is not perfect. The layer height is better than 0.2mm and a 40% fill is what I have used, and it is important to use supports to use TPU
