Summary

Modified a container to make 3 sizes of a portable pill/ medicine container that use an ordinary water bottle cap to close. Has very smooth threads and closes tight. The caps in the photos are Smartwater brand but others work as well. Each size has a loop for a lanyard or key rings.

Print settings I used:
0.12 layer height
35% infill
No brim or support needed

This is in fact a remix from a different site I cannot even find anymore for some reason, Deleted maybe? Original is the smallest one but without the loop for keyrings, I also changed the internal space to hold more and also the grip on the outside.

Enjoy!
