This bumper-style case is designed specifically for the Sony Xperia Z3 Compact, giving your phone edge protection without covering the whole back. It's one of those 3d printed tech accessories that bridges function and flexibility, printed on demand, just for you.

The design is fully parametric and built in OpenSCAD, so every dimension is adjustable. The creator has commented the code thoroughly and shared the source on GitHub, making it a great starting point if you want to tweak the fit or adapt the case for a different device with a similar shape.

Because the design evolves on GitHub, you're getting a community-backed file that's been refined over time. Perfect if you love tinkering or just want a case that fits like it was made in your workshop.
