Fluttering Butterfly

The original design is great but I created this remix with just a few subtle modifications that worked better for me.

1) In the original design the hole for the pin in the bottom section seemed too tight. I had a hard time getting the pin through and it didnt spin as easily as it should so I enlarged the hole and the surrounding collar slightly

2) I also wanted to avoid the need to use superglue because I can rarely ever use the tube of glue more than once. No matter how carefully I clean the cap it often gets glued shut. To get around this problem I squared off the tip of the pin and squared the hole it fits into in the top piece. This prevents rotation between the parts. Then instead of using superglue I was able to use locktite and because I made the fit very snug I didn't even have to wait for it to dry more than 10 minutes

3) One last thing, not a mod to the print but to the assembly. I didn't really want to work with cutting such a small piece of aluminum for the bushing so I
