mesh kids neck tie
I changed the kinematic bracelet into a small tie. .2mm layer height. I scaled it up to 110% and turned it diagonal to make it as big as possible while still fitting on my build plate. It has a button slot on the back that fits over the top button of the shirt. Only works with thin buttons.
UPDATE: I added a newer version with a new tie looking top piece. it looks like an actual tie knot. it has a hole going through it that you can string some thin elastic through or whatever you want to use.
