V-Twin Motor Fidget!

A print in place (mostly) solution for a 90° V style engines, including 2, 4, 6, and 8 cylinders!  A fun fidget toy that's fun to play with and fun to look at!

**Update 5/2/25

Added versions with a crank handle, a grip for holding, and enlarged crankshaft journals

The part prints mostly complete, however in order to avoid support materials, half of the pistons are printed outside of the engine block lying flat on the printer.  Once the print is completed work all the joints to get them loose and movable, then pop the extra pistons into the cylinder block and you're off to the races!

Remixed from Mars3D original Motor fidget.
