Easy as PI locking container
thingiverse
This is a revamped version of 2robotguy's easy as PI design found here: http://www.thingiverse.com/thing:3817. The original model was redesigned due to some issues, such as the locking ball often breaking and improper functioning of security rings. To address these concerns, I made several changes: the locking ring is now a solid square, the lid's wall thickness has been increased, and the top ring is slightly longer to prevent easy removal. This container will be used for a custom geocache project. For printing, give the rings a light sanding to remove ridges, then print with 0 shells and 100% fill at .27 layer height for optimal results.
