/*
I want a HEAVY phone stand, so that my Mum can use her phone one handed.
The weight is achieved by filling it with plaster / sand / cement / lentils...

Note, the model is almost entirely hollow, apart the the "ledge".

Drill a hold in the back near the top
Add dry plaster or sand & cement.
Add some water,
Plug the drill hole with a (3D printed) bung if you want!
Glue non-slip matt material to the base, and the front, where the phone sits.

Beware PLA will almost certainly crack, if dropped onto a hard surface.

Print Notes
   Consider using enough perimeters and top/bottom layers so that
   `thickness` is completely solid.
   e.g. with a 0.4mm nozzle, and a thickness of 1.6mm, use at least 4 perimeters.
   And with a layer height of 0.2, use 8 top/bottom solid layers. 

    Fill % can be low (remember the model is mostly hollow anyway!)
