Modular rainbow wind spinner, print as few or as many levels as you like. Includes a wind vane. Spins even in a very ligCC BY SA NCht breeze (GIF is from a video shot in 2mph wind)

Mounts on an M8 threaded rod (mounting blocks included), use one 608 bearing and four M3x16 screws and heat set inserts per spinner. The included spacer will separate layers and keep the nuts on the threaded rods from binding the spinner. For a 7 layer full rainbow you will need a 1M long M8 threaded rod and nuts to go with it.

Print in PETG for or better for UV resistance.
