Inspired by the Bedside Phone Shelf by TheSoup I created this one from scratch in Tinkercad. It is specifically sized to fit onto the side of my bed (which has a 20mm edge) and for my Samsung Note 8 phone to rest on. I'm actually surprised by its strength - it can also support a 1L drink.

This is specifically designed to be printed upright and takes very little infill due to the slopped design of the end (top).
