d20 Wound and Experience Tracker
thingiverse
I was after a simple yet elegant solution for holding two 20-sided dice to mark wounds and experience for the board game Gloomhaven. I intended to design something of my own, but found Jambro's "Large D20 Holder" which fit the bill perfectly. I edited the "top" file in Sketchup Make and resized it to suit most d20s in my personal collection. Now I can use d20s without worrying about an errant bump changing values. I'm sure others can improve on this design but for now, it suits my needs just fine.
