A popping cork style float

The final version of the popping cork float. It's got a concave surface that ought to really make it pop. To put it together, you'll need a couple of beads, some stainless steel wire, a few ball bearings (to be put in the body as it's printing), and a swivel. And the printed float. Mustn't forget that.

Print the float out at 0.2, with outer thickness at 1.5 mm and 0% infill. Drop the BBs in while the print is running. Then, assemble as shown in the incredibly detailed and magnificent instructions provided.

Just an FYI, it's meant to be printed with the concave face down.

Enjoy.
