X4 Cults3D Why this is the one to get for phone-back carry: The ring-slot folio is the only design that physically locks the magnetic ring into the case — no adhesive needed, no ring sliding.
Slim Everyday Carry Cases
TPU = flexible and impact-absorbing. PETG = semi-rigid and more scratch-resistant. Both work; pick by your printer and preference.

Print Material Guide
Pick the right filament before you hit print — the wrong choice makes the case brittle or too flexible to stay on.
| Material | Rigidity | Best for | Notes |
|---|---|---|---|
| PLA | Rigid | Slim snap-on cases | Easiest to print, cheapest. Fine for indoor carry. Brittle in heat or drops. |
| PETG | Semi-rigid | Most cases | Better impact resistance and temperature tolerance than PLA. The community default for X4 cases. |
| TPU | Flexible | Folio and full-body cases | Absorbs impacts well. Harder to print — requires slower speeds and a direct-drive extruder. |
Platform Comparison: Where to Find More
The X4 print community is active across four platforms. Here's where each one shines.

Frequently Asked Questions
What is the best 3D printable case for the Xteink X4?
For most owners, the X4 Full Body Case by fusselich (MakerWorld, 1,600+ downloads) is the most complete option — it covers every surface with a raised screen lip and covers for every port. For a slimmer carry, the Osaka System clip-on case (Printables) is the most-downloaded option on that platform. For phone-back magnet mounting, the Monke CAD ring-slot folio (Cults3D) is the only design with a built-in ring pocket.
Should I print an Xteink X4 case in PLA or PETG?
PETG is the community recommendation for most X4 cases. It's more impact-resistant than PLA and handles everyday carry temperatures better. PLA works for snap-on clip cases but can crack under stress or warp in a hot car. The full-body case by fusselich is specifically tuned for Bambu Basic or Matte PLA — if you're using a Bambu printer, follow the designer's recommendation.
Is there a 3D printable case for the Xteink X3?
Not yet — the 3D print community has focused entirely on the X4 so far. If you own a printer and want an X3 case, the closest starting point is the Zorian22 X4 reference model (Thingiverse), which documents the measurement methodology you'd need to replicate for the X3. The X3's smaller size means X4 files will not fit.
