Pill box keychain middle for infinite stacking (big)

An addition to my keychain, to make it infinitly stackable!

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

It's a bit bigger therefore multiple/bigger pills or vitamins would also fit in here. 

A big lid allows it to be more easily opened.

With a little smiley on the inside, just because :)

I might upload different iterations in the future :)

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

33mm wide (excl loop for chain) 26mm high (if you don't stack them)
