Air Spinner

I'll admit that this is sort of a fidget spinner - but just barely.

My nephew discovered the whole Fidget Spinner + Air Compressor thing and promptly locked up all his bearings. This is designed specifically to use a single skate bearing, and. of course, to be spun by air.

I may do a bigger version later to be set on a pole in the yard. - might. That would need a "hat" to keep the bearing dry. That pretty much depends on how quick he gets bored with this one.

Well - he thought the first version was cool so we did a second version with slightly canted arms. If you spin it up with an air compressor on a shaft it will climb the shaft (theoretically - we are still printing it).
