v2: Increased brim height to act as a bumper for the screen. The original version is still retained if you prefer a lower brim.

A 3D printable case for Unihertz Jelly Star, the mini Android phone.
One of the main complaints I have had about the Jelly series is the lack of a case with matte finish. The official TPU case that comes with the phone tends to get extremely oily, while I am also not able to source any good third-party case that has a matte finish.
As a result, I ended up designing this case on my own with OpenSCAD. There are a few things to note before printing your own:
- This model is intended to be printed with flexible materials like TPU.
- It is slightly smaller than the actual phone, so if you print with a rigid material, it will probably not fit.
- The intention is that the case will stretch a bit to ensure a tight grip on the device.
- Print with a clear TPU if you still want to see the LED on the back.
- Print slowly to ensure good overhang performance.
- On my Bambu P1S, I had to lower the volumetric speed to around 1.2 - 1.5.
- This is mainly due to the curvature of the case / device. The model has already compensated for that by making the back much flatter than the device itself, but it is still not a easy print.
- The geometry of the case is manually created and calibrated.
- As a result, it will never be an exact fit, but for me it works well enough.
- More specifically, the back of the case does not follow exactly the geometry of the phone.
- There is no lanyard hole because I don't yet trust the case to hold the phone well enough to not slip when hung. It should be straightforward to make a remix with a hole for that though.
- This model will not work with the older Unihertz Jelly 2 or 2E – however it should be relatively easy to adapt for them.
