This was a fun quick procrasti-project. It's double-sided too (it's a blinking question mark after all)!
I don't have a multi-filament printer so I implemented a satisfying no-glue snapidy-snap system to print the distinct black and white parts (but there's also a file in there if your printer can do multi-colour!)
It can also be a luggage tag, or keychain, or just a fidget token (it's got a nice heft to it).
