Windmill - Pinwheel Optical Illusion

A great design by Dalpek and remix by CBC. This remix uses CBC's prints in a windmill application.

I enlarged the pinwheels to 186 mm diameter. Cleaned wheel center hole with 1/2" drill bit in a drill press. Take some time to smooth up the blades. Press in the bushing & install bushing washer.

Wire:
Wire clothes hanger (2.4mm) or 3/32" brass welding rod (2.5mm).

Try for balance between tail & blades by moving the blades. Spacer between blades may be necessary.

Drill sizes used:
Pinwheel center hole 1/2" drill bit
Pinwheel bushing center hole #39
Nose cone center hole #42
Holes in the frame for wire inserts #42
Frame mount #35
Frame tail hole where filament is used #49

Glue where necessary.
