This holder works for phones with or without case. I use this holder for my minimalist wallet. You can also use this holder for credit cards and keys.
Step 1: Tools & Supplies
- Bicycle inner tube (of 2.2" MTB tire)
Step 2: Cut the Inner Tube
- Cut approximately 0.5 mm of the inner tube. You'll need two of these.
Step 3: Assembly
- Loop one of the inner tube crosswise from the corners; upper left corner to lower right. First croswise loop will serve as a base grip which will prevent slippage. It is especially useful for the phones/cases with slick surface.
- Do the similar for the other corners. That's it.
Loops do not affect the functionality of the buttons (with or without case).
