Josh's Customizable Z Fold5 Phone Case

I mostly enjoyed using Samsung's S-pen compatible Z Fold5 case, but it had a few downsides. After the top of the front case near the speaker cutout broke, I decided it was time for a new case, with some upsides!

I present to you Josh's Customizable Z Fold5 case! 

The S-pen holder is gone, which both increases printability and prevents the S-pen from fallout out and getting lost. 

After too many revisions, the speaker and microphone cutouts and nearly perfectly centered. The camera bump cutout is also nearly perfectly centered and fairly snug to prevent excessive movement of the back case. 

The power button and volume rocker is exposed to allow for easy access. 

The front case has shallow grooves in the sides for applying adhesive putty or your adhesive of choice. I used this: https://www.amazon.com/dp/B0CXHFP3J2 (See update below for a version that does't need adhesive!)

My case was printed out of White Overture PETG and Translucent Red Polymaker PETG using the 0.20 mm Quality preset and a slightly tuned filament profile on a MK3S with MMU2S and a textured print sheet.

The QR code, text, and fuzzy skin was applied using PrusaSlicer. Make sure to open the .3mf files as a project if you want to use my pre-applied paint-on fuzzy skin.

If you have any question or suggestions, please feel free to reach out!

Update 11/27/2025:
I added two models and moved the .step files to a folder to unclutter the files tab.

The first model is a v2 of the case front that stays on without needing adhesive putty by being held in place by a tempered glass screen protector. I used this screen protector: https://www.amazon.com/Supershieldz-Designed-Fold-Friendly-Protector/dp/B0C62J7CQ3

The second model is dimensionally similar to the original case back but it has a cutout to hold two IDs and/or credit cards. Having cards in the cutout interferes with the phone's ability to wirelessly charge and the card's ability to perform NFC actions.

So far, trying to print both TPU and PETG/PLA has compromised the printability and quality of the case beyond acceptable limits. 

Drops from above 2.5 feet (76.2 cm) onto stone tile are enough to crack whatever part of the case hits first, but prevents damage to the phone. At $15/kg, the material cost of a single color case is $0.12 for the case front and $0.51 for the case back, for a total of $0.63 for a complete case. At this low cost I consider the case to be a comsumable and expect to replace it as often as it is dropped/knocked onto the floor.
