This is a derivative of the 'Mini Programable Cryptex'. The changes are designed to make the thing easier and quicker to print as the original had significant overhangs on the text and the internal part. The more problematic overhangs have been removed. New ends have been designed to stop scratching the tumblers. The tumblers are round as opposed to having flat faces. The text is recessed rather than protruding for a neater and more robust finish. The inner part has been split into two, to make printing of the fingers easier and more precise. An option on the inner tube now has a closed end to provide a larger area for adhesive thus more robust to handling.
STEP files are included to allow you to readily modify this version for yourself.
