Pretty impressed how well that one turned out. Used SUNLU TPU in yellow with 200/50 degrees Celsius at 20mm/s speed on my Voxelab Aquila (upgraded PEI bed and DirectDrive, also used Filament drybox).

This filament to be exact:

Very nice. Did you model this yourself? If so, did you also have to model your phone or were you able to find a dimensionally accurate model somewhere else?

    Not this one, but today I made one for my iPhone 13 Mini. I just measured the hell out of my phone, directly started with the case model and hope it will fit once I print it (probably tonight, as I am currently printing a new fan shroud I designed around a standard Satsana). For easier things I often manage to fit on the first try, but as it gets more complex, there are more prototypes.

    Thanks for the follow up/link. I don't have an iPhone 13 mini, but I am going to have a bunch of spare TPU soon and you got me thinking. As you said, it can take a bunch of iterations to get a great fit. I was curious if you had a secret sauce, but hearing that we follow a similar process was comforting.

    It’s not perfectly easy, but if you are a little used to 3D programs like fusion360 and have a caliper, it’s perfectly doable. Oh and this here helped me getting the curves right:
