I made this to keep my iPhone from sitting on the floor or dangling from the cord. It fits nicely around the charging dongle.

I started with a fairly solid prototype, but needed to make some changes:

  1. Made the wall charger opening bigger.
  2. Added lots of holes to reduce plastic usage / print time.
  3. Shrunk the thickness of the platform to 2mm from 4mm.
  4. Added a fillet to the bottom for better stability.

The next revision should be a hexagonal plate so there’s no need for infill around the holes. That would really make things more efficient.

I built this in OpenSCAD. Prototype 2 took 1.5hrs to print on a MakerBot Replicator 2 with a 5% infill and 0.30mm layer height.
