Stackable Wind Spinner

A stackable wind spinner/whirlygig to hang in your garden. There are two main models, which spin in opposite directions. They can be stacked by placing a swivel between them so that they can spin independently. I used #4 ball bearing snap swivels between and at the top. I bought the swivels at Walmart, but they are also available from Amazon. The top and bottom of the spinners are threaded. There is also a screw in plug for the bottom if you don't want to stack them. The threaded stud screws into the bottom to accept a cap in case you do want to stack them. This is an easy print, no supports or AMS needed. The models are scaled to 80%, which works well, but it should work just fine at 100%.
