Just finished my first TPU print - Lemmy.world

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: Angebot: SUNLU TPU Filament, 1KG Flexibles 95A TPU 3D Drucker Filament 1.75mm Maßgenauigkeit +/- 0.03 mm, Hohe Liquidität und Elastizität, 1KG（2.2Lbs) Spule, TPU Filament für FDM 3D Drucker,TPU Gelb https://amzn.eu/d/7H5TLjr [https://amzn.eu/d/7H5TLjr] [https://i.imgur.com/jJka7d9.jpg] [https://i.imgur.com/jHmmnf4.jpg] [https://i.imgur.com/ztlGg6g.jpg]

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:

Excellent link, thanks! And yup, time with calipers, fusion360, and practice gets you there.
