Upgraded case: GermBrella

Upgraded phone case designed for polymer technology project. Casing features strips of silicon nanopillars (added on using reactive-ion beam etching) that have antibacterial properties. Nanopillars measure 500nm in length, 50nm in thickness, and spaced 100nm apart. Case without the nanopillars can be 3D printed in a single step.

There are 2 STL files here (under Thing Files) - 1 with dummy curves where the silicon will be, and the other is just the case without strips.

Casing weighs 23 grams and polyurethane is the material used.
