it's an adapter that lets you use 1/4" hex bits in tight spaces. You can turn it by hand or it will fit in a 12mm socket or wrench. This prints about perfectly on my tevo tarantula. The bit is slightly loose. you can always copy and modify the tinkercad design if it doesn't come out perfectly for you. This thing was made with Tinkercad.
