Cuttlephone is a phone case generator for 3D printing. It's designed for playing games with your existing phones. It currently supports the Pixel 3, 3XL, 3A, 4A, and Galaxy S9+. The project is open source and I plan to add support for more phones with help from the community.

Do you have a 3D printer? Are you interested in making a phone case? Let me know what you think of the project. 3D models can be found on the Github site, Printables and Thingiverse. My build log with more pictures is on Hackaday.io.

Hard plastic (PLA+, ABS) or flexibles (TPU)

The generator is written in OpenSCAD and heavily uses the customizer features. The build script makes 3MF files for each phone and case type.

Here's my daily driver - A Pixel 4a case with Junglecat rails printed in TPU. I just went on a trip and played Prinny: Can I Really Be The Hero? in the airport.

Here's an old pic of the Joy-con rails printed in PLA+ for a Pixel 3. Unfortunately Joy-con support in Android is crappy. Some emulators (RetroArch, PPSSPP) don't support input from 2 devices at once. Dolphin emulator handles it at least. My phone got the infamous Joy-Con lag which made these unusable. I haven't tested Joycon rails in TPU yet.

If you print this yourself, the rails must be removed with a blade, leaving about 2 layers of plastic. I do this by hand and it's tricky. Soon I'll make a tool for guiding the knife.

This is awesome, do you think it would be possible to work on a universal (telescopic) design for the case?

edit: forgot to say, maybe you could take the Ipega 9167 as inspiration?
edit2: or even better, the Betop H2?

Ya know, I thought somebody did that already. I found one on Etsy for sale but no free models. I'll check it out. I can easily make something that holds on with a rubber band

Here's what I came up with. It holds on with a rubber band or hair tie. I'll work on this more later and add a rail. I'll be more motivated if people post prints ;) Files are all available now as "Universal 2-piece" on the website

New generator feature. If the case thickness exceed the Junglecat rail thickness, these wings get added.

And Joycon of course. I may make this longer so that the Joycon stops at the bottom.

In the generator, "manual supports" are set to none. I'm printing vertically so that I don't need to cut away the manual rail support. I'm using paint-on supports in PrusaSlicer and they pull off easily with tools. The Joycon is still a little loose, I'll keep tuning it.

The telescopic clamp is ready. It's called "Universal Telescopic" and models are available on the website.

Here it is holding a Pixel 3XL in a slim case. I tried printing Joucon rails facing down on this one. The telescopic rail came out great (no supports to remove) but the Joycon rails failed.

It's rubber band powered. This design is too large for a hair tie. This translucent filament shows the sliding mechanism. This sliding part may need sanding for a smooth experience, especially with support leftovers.

The outside of the sliding mechanism has an angle to hold that rubber band. The inside of this has a wedge shape to hold various phones.

The generator has more customizer settings under the section "universal phone adapters". The "telescopic" checkbox activates the sliding feature. Clearances for the sliding rail are here. "body_chamfer" replaces the inside radius with the wedge (EDIT: I'm moving this checkbox to the "body" section). The overall size and the inside shape can be controlled in the "body" section and "screen" section.

In the slicer you must separate the two parts. Add manual supports for the telescopic rail and the gamepad rails.
