It's a very straightforward model. There's also a bigger version on my profile:)

The lid screws on the outside to prevent pills from getting crushed. 

A big lid allows it to be more easily opened.

I might upload different iterations in the future :)

Printed these with 0.1 resolution 20% infill, both were printed with the flat side down.

It's 24 mm wide (excl. loop for chain) and 16 mm high
