What it does

  • Parametric design: customize the size to fit your exact phone model
  • Attach your own elastic band for a comfy, adjustable fit
  • Lightweight, wearable holder keeps your phone secure during exercise
  • Open-source OpenSCAD file included, tweak and remix as you like

Meet the armband that actually fits your phone. This 3D printed tech accessory is built around a clever parametric design: adjust a few values in the OpenSCAD file, and you've got a custom cradle that hugs your device perfectly. Whether you're running, biking, or just need hands-free access, this holder keeps your phone snug and ready.

The armband works with any elastic band you stitch on yourself, yes, even if you've never sewn before (the designer hadn't either). It's a fun little DIY project that pairs digital fabrication with old-school craft, and the result is something totally yours.

Future modders, take note: the design is ripe for tweaks. Round the mounting profile for extra comfort, add curved walls to lock your phone in place, or dream up a sealed version for rainy-day runs. We print it custom for you; you make it your own.

What it is made of

Designs like this print well in PLA. Compare the materials.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
