Konami Lock Ring for Master Lock 1534D

Master Lock makes a “Combo Word Lock” 1534D that is designed for customizable keywords as the unlock code. They provide some basic letters and symbols.

This design contains one Fusion360 Project for customization, and one “Konami Lock Ring” the has the ↑ ↓ → ← as well as A, B, square, circle (start), X and Y, which can be used for the now famous Konami Code.

I've used enamel paint to fill in some of the symbols for better visibility.

I'd suggest printing in 0.1 or 0.2mm layer heights, and 4-8 perimeters. I used supports as they auto generated with the lip side down.

I printed in PLA, as this is for an indoor escape room.

I'd not suggest that these are as strong as the originals, so don't expect full “level 4” lock strength as is suggested by the manufacture. 

Also to note is that you need a very well tuned printer for this print. Even a slightly misaligned layer will cause issues with the fit.
