A template with the minimum and maximum diameters for a Nova G3 chuck. Allows you to quickly see if you piece is sized correctly. Has a slot to allow easy pegboard hanging.
Note: In the photos this is 1/4" thick. That was a bit of overkill and the .stl attached is 1/8."

This should be fine at 25% infill. I just forgot to change that setting before I printed it off.
Took my calipers to my G3 chuck. Measured the inside diameter of the chuck at it's smallest, and the outside diameter of the chuck at it's largest.
