This is a woggle used to hold a scout scarf closed. Its the Australian Scout Symbol made 3d and put on a ring. The default sizing is good for the smaller kids scarves and to make it for adults, upsize it by 20%. I made a bunch of these and then did a scout program that was all about computers and did a quick show of how I made the woggles and then gave them all one at the end. Looks great made from glow in the dark filament!Simply print and then glue together with Acetone. The two pieces are separate for easier printing.
