Rattle toy on a chain and foot toy for birds

https://youtu.be/P1M-zeE6ots A toy meant to twist into fine wire from "breeder" or flight cages made of roughly 0.5 inch wide welded wire. The foot toy works for any bar size, scale it up so it is large enough not to fall through or be wedged in the cage bars. After making a 3D print for a bird, run a lighter over the print to make sure all the filament strands are fused together. A loose strand of filament could become an entanglement hazard. To free the bead inside the rattle, ram it with an unfolded paperclip, and with some effort, it will pop off and make a rattle!
