6-Cylinder Amish-Style Wobble-Plate Air Motor

Six-piston pneumatic motor: pistons push a wobbling disc on the
 crank; a flywheel smooths the run; a rotating cone valve with one
 port fires each cylinder every 60 degrees, offset from the wobble
 for correct timing. Great desk demo; tune pressure and fit for your
 setup. Designed in FreeCAD; printed in PLA.

- modeled in FreeCAD.

- parts intended for 3D printing in PLA (adjust slicer
 settings and tolerances for your printer; Bambu A1 mini or
 similar).

-  Working six-piston compressed-air motor with a wobbling thrust
 plate driving the crank, a flywheel for smooth rotation, and a
 single-port rotating cone valve that sequences air to each
 cylinder. Layout evokes traditional Amish shop air motors -
 compact, visible motion, satisfying on shop air.

 - Six-cylinder, single-acting air motor.
 - Pistons bear on a wobble (swash) plate; disc wobbles with the
   crank to turn the shaft.
 - Flywheel smooths rotation between power strokes.
 - Air timing: rotating conical valve with one opening, phased to
   each bore in sequence.

- Timing / geometry:
 - Six cylinders at 60 degrees spacing.
 - Valve opening phased 60 degrees from the wobbling disc so
   admission matches piston stroke (defines direction and torque
   feel).

 - All six pistons pumping; wobbling disc and crank turn together;
   flywheel steadies motion; cone valve "plays" each cylinder like
   a mechanical distributor.

 - Liberal tolerances on bores, piston OD, and wobble interface;
   only very light sanding may be needed, depending on your printer.
 - Orient sliding surfaces for low friction where geometry allows.
 - Light oil or suitable dry lube on pistons, disc, and bearings
   for first run.
 - Start at low regulated pressure; short bursts while checking
   bind, leaks, and valve alignment.

 - Compressed air can produce sudden torque. Use regulated
   pressure, eye protection, secure the motor, keep hands clear of
   flywheel and moving parts.
