/diy/ - Do It Yourself

Circled in red here is a worm screw that should come out with a small allen key. Once it's removed, the shaft should pull out to the side, and once the gear itself comes off the shaft, the other gear that's meshed to it should move as well. There may be a second worm screw in that second gear, which frees it from the vertical shaft.

Once those gears and shafts are removed, the rest may readily come apart. If not, there could also be screws in the sides where the bottom cup piece meets the top axle support piece.
