Summary

As you can see from the remix sources, I've simply taken a couple of models two others have shared and combined the two in a way that amuses me.

I made this for my Tevo Tarantula's extruder motor and because the shaft sticks out to the side, it gave me the idea to hang some sort of pendulum from the turning valve handle to add some additional motion/whimsy.

The two shafts are very thin so if your printer has trouble with things like that, it would be best to print so those parts are horizontal to the print bed. I printed mine with the nose of the ship pointing up and the valve positioned flat with the crank vertical. The sphere has a little bit of a flat side so that is faced toward the bed.

After printing I cleaned the parts a little bit and sanded the end of the crank and flat side of the ball. Once everything was poorly painted with Posca markers, I put the ship on the crank and glued the ball to the end of the shaft.
