The 3D printed parts are fairly easy to make with most common home desktop 3D printers that are on the market.

And if you don’t have access a 3D printer, you can order our parts by visiting our Thingiverse page and have someone local 3D print the parts and ship them to you.

This case design is only for flexible material! It will not fit an iPhone if it's printed in hard plastic!
Files for the PLA version are listed below!

Flexible Filament

TPU (thermoplastic polyurethane) filament is a flexible material that's ideal for gaskets, plugs, leveling feet, and mobile phone cases! There's different types of TPU, some which more elasticity than others and others with more grip. 

Settings for Flexible Filament


  • 240C Extruder Temperature
  • 65C Heated Bed (glass, PrintInZ, BuildTak, kapton, etc.)
  • Blue Painters Tape for Non-heated Bed
  • 30mm/s default print speed
  • First Layer, Top and Bottom Layer Print Speed: 50% of 30mm/s


3D Printer & Slice Setting


TPU filament can be rather difficult to 3D print. Follow our recommended settings below for a good starting point. We've found TPU works best with direct-drive extrusion, however bowden style extruders with 2.85mm diameter will work fine.


Print Hotter


TPU extrudes best at 230C-245C temperatures. It has a higher melting point and requires more heat than regular PLA or ABS.


Bed Adhesion


65C temperatures for heated beds. For non-heated beds, blue tape works well.


Printing Speeds


30mm/s for default printing speeds. 50% slower for the first, top and bottom layers. A slow print speed allows for better layer bonding and good adhesion to the bed.

Clean up


We used a flush diagonal cutter to clean up stringing  around the port openings and around the enclosure. 


Make sure the openings for the slide switch and Lightning ports are cleaned before plugging in cable. Use a hobby knife to help cut away stringing that could block the volume switch. 

PLA Filament

Slice Settings


Download the STL file and import it into your 3D printing slicing software. You'll need to adjust your settings accordingly if you're using material different than PLA.
