The StashCan is an imitation soda can with a programmable combination lock on the bottom of the can and a sequential puzzle lid which prevents unauthorized access to the can's contents.  Super fun and super detailed.  This new version 2.1 has updated files, instructions and support for AMS so that the combination on the bottom of the can is more visible.  But it also prints well without an AMS.  

It is 100% printable, and no hardware fasteners or adhesives required.  

It is a fun, hide-in-plain-sight storage solution with added functionality thanks to the combination lock. While it is not entirely secure due to its portability and plastic material, it provides an enjoyable and challenging experience.  It is going to likely be the most complex thing you have ever printed.

This is an advanced model with many details, so please refer to the documentation on my blog at https://www.logicalplanet.com/ and watch the accompanying video before attempting this print.
