"It's not a bug, it a feature"

While trying to design a phone stand I accidently made a phone stand that won't hold you phone. It's spiral shape and curves allow it to twist and slide out from under your phone.

This was designed for for small phones (approximately 2.5in * 5.5in (6.5cm * 13cm)) If your phone is bigger scale this model up by 25% or 50% or whatever to fit you phone - bigger tends to work better.

There are a few angles when the phone is actually held by, but these tend to be very precarious and a light touch is often all that is need to destabilize it. It works best when placed on smoother surfaces and when a phones is in a less grippy phone case. It is also more slippery when it is lighter - less or low infill.
