Flyswatter-Wire handle

Just grab a metal wire hanger, untwist the hook and cut off the twisted ends.

Straighten out the wire, bend the wire in half around a sharpie or something round around 0.75" in diameter.

Feed wire ends through the two holes in the 3d printed mesh until the wire bottoms out. Then twist the wire until it's nice and tight.

Viola! Now you're a fly killer. Get 'em Ace!
