Samsung S4 spare battery cover

I often carry a spare battery in my pocket. Contacts covered with a small piece of tape.
This is a more elegant solution.
The print has a tight fit and will not fall off.

Designed to be printed with a 0,6mm nozzle = 2x0,72 mm for the walls.
If you want to print this with a 0,4mm nozzle, manually set the track width to 0,48. This will result in 3 outside walls.
Layerheight for the print was 0,2mm

Enjoy!
