I could have nicked some dice from the kids board games, but why do that when you have a 3d printer!! When searching on thingiverse for models to print out I found a dude had created these: https://www.thingiverse.com/thing:1040397 which are to help you randomly choose a key or chord and its variants. I printed a set of those along with some normal 6 sided dice (does anyone ever play the 7th chord in a key?!?!?)... and voila! Instant inspiration
