About this model

A press-on knob for the release screw on the bottle jack used in the Harbor Freight 20-ton press. It also appears to be the right size for the same knob on the 2-ton engine hoist, though I haven't tried that. I'm including F360 and STL files in case you want to modify. Video of build here.
