10 letter Cryptex

#Introduction
This is a re-programmable 10 character cryptex tube.
I made it for a puzzle challenge that I was running. I couldn't find a 10 character one, so I made this. It is re-programmable so that I can use it again another day with a different password.
The plastic springs give positive feedback to assist with lining the letters up - I'd imagine that printing them with a different filament would change their 'clickiness' - the PLA made for quite a robust click! :)
It does not hold a lot, but I think it looks cool!

All parts are printable without supports as long as your printer supports 45 degree overhangs or the occasional bridge.

#Disclaimers
It is made using inspiration from all over the Internet.. Hopefully no toes were trampled in the making thereof.
It makes a good chunky paperweight! 300grams or so!
