thingiverse

The champions of modern makerspaces have their creations decided by a simple "thumbs up" or "thumbs down" verdict.\r\n\r\nNow your 3D printer will serve as the ultimate judge and jury over your prints.\r\nAs filament flows through, the thumb of fate will spin wildly, and where it finally stops only your printer will reveal the truth.\r\n\r\nEngineered to fit snugly around a Nema 17 motor with a 5mm diameter shaft.\r\n\r\nFor a fun test, but also to ensure the motor is functioning smoothly and retraction is working perfectly. \r\n\r\nPrint it face up with support, and if necessary, carefully enlarge the hole to achieve a snug fit.
