Phone Case Generator for 3D Printing
Pick your phone, the material and the case style, give the back a pattern and download the case as an STL. The geometry is built in your browser from the device profile, with no upload and no account.

A case built from the device profile, not from someone else's STL
The generator builds the case from the phone's outer dimensions, the fit clearance and the wall thickness. In TPU you get a flexible case with a continuous screen lip; in PLA a rigid case with open areas and short retention tabs, because PLA does not stretch over the phone the way TPU does.
The first supported phone is the Motorola Edge 50 Pro. Its outer dimensions come from Motorola's official specifications; the openings for the camera, buttons and ports are deliberately generous.
What you can customize
- Choose the device by manufacturer and model
- Material: TPU 95A, PLA or your own values without a preset
- Case style: Standard, Slim, Protective or Bumper
- Back: solid, grooves, raised ribs, round holes, hex holes, honeycomb, slots, diamond or grid
- Fit tight, normal or loose, or as a number in Expert mode
- Screen lip, normal or raised camera protection, corner reinforcement
- Buttons open, or covered in TPU
- Bottom with a wide opening or open
- Warnings for thin webs, an over-perforated back and the build volume
- Fit-test STL: the bottom 30 mm of the case to try first
How the Phone Case Generator works
- Choose the manufacturer and model.
- Choose the material and case style.
- Set a back pattern and the protection options.
- Print the fit test first and try it on the phone.
- Adjust the fit if needed and download the full case as an STL.
Printing tips
The case prints back-down without supports. Only a raised camera lip stands out on the bed side and needs support.
- Print TPU slowly, around 20 to 30 mm/s, with little or no retraction.
- Print the fit test first, then the full case.
- With raised ribs, good bridging settings help.
TPU or PLA?
TPU 95A is the material for phone cases: it stretches over the screen lip and absorbs knocks. PLA is stiff and brittle. The generator builds a different geometry for it, with an open bottom and short retention tabs between relief slots, so the phone goes in without force.

Frequently asked questions
Which phones are supported?
To start with, the Motorola Edge 50 Pro. More models are added as new device profiles.
How accurate is the fit?
The device's outer dimensions are officially confirmed. The real fit still depends on printer, material and calibration, which is why there is a fit test and a fit setting.
Can I print the case in PLA?
Yes. The PLA version has an open bottom and short retention tabs instead of a continuous lip, because PLA does not give like TPU.
Is anything uploaded?
No. The geometry and the STL are created entirely in your browser.
Your phone. Your material. Your case.
