Number Safe - Cryptex (no Supports)

This is an upgraded version of my original design.A larger version with 6 digits is available here.Improvements over Version 1:no supports requiredtighter tolerancessmaller while keeping the same storage volumeA number safe with an adjustable code that you can use for a creative gift box.You can set the code by pressing the number rings onto the lock rings. Make sure the number you want is aligned with the hole.When all four rings are in place, you can use a little glue to attach the end cap. There is no load on the end plate, it just prevents anyone from seeing the lock mechanism.Have fun!
