Enigma Puzzle Box with larger dial / better grip

With the original model turning the dial is a big hassle. You need to turn it quite forcefully but don't have enough grip to do so.

I imported the dial into Fusion 360 and made the following changes:

• increased the height of the wheel from 1.5 to 5 mm, providing a larger surface area to grip it
• designed a grippy surface much like a knurled-head screw
• smoothed the groove, which is the actual locking mechanism, by adding fillets to every bend

Now everything works really well. It is possible to turn the dial and clearly get feedback whether you actually can turn it or not. No need to lubricate anything.

This 3mf file contains everything from the original model with the exception of the dial, which has been changed to my improved version.

Instructions for printing and assembly can be found in the original model: https://makerworld.com/en/models/95054#profileId-110127

Have fun!
