Gaslands Game Tracker
This very handy do-dad is from jpri69 on Thingiverse - it's a "Gaslands Game Tracker".
Just print it out, add a couple of D6 or a D6 and a D10, depending on how long your games tend to last.

This is the one I printed out on my Creality CR-10 (using PLA, 0.12mm layer height at 20% infill), fully populated with dice.
I may paint the lettering at a later date but to be honest it doesn't really need it.
My new best friend... a pack of metallic Sharpie markers!
