Breakout EDU Key Clue

For use with Breakout EDU. Print chips in whatever colors you wish. Print Key white or light colored and use Sharpie or paint to color the dots to match the lock combination. :Hide just the necessary chips or add a few extras (different colors, of course!) for additional challenge! I've only made number chips so far but this would also work with letters or symbols!

Credit goes to BreakoutEDU member Jeff Hennigrant for the Breakout Logo and to Thingiverse member Belfry for the bottom half of the key, Thing #52761 .

Feedback welcome. Encouraged, actually! How could this be better?
