This little momma employs a couple modern key features that make it work so well.

1. No hardware, and uses standard TPU filament for the cord!
2. Snail's re-mastered design allows for the BullRoarer to spin freely to prevent the TPU from twisting and tangling. (This is a common design flaw in all BullRoarer's I've seen on the market and renders the call ineffective after enough spins)

Printing Instructions: BEGINNER LEVEL EASY! (see listing photo)

No supports // .2 layer height // 15% grid infill // 2 walls // 5 top layers // 3 bottom layers. These are the correct settings for all three parts. *Note: it's important that this BullRoarer itself weigh roughly between 30 and 35 grams, too light and you won't have momentum, too heavy and she won't spin well. The mentioned settings should achieve the desired weight. ( tip: *import and slice the Roarer by itself and see the estimated weight in your slice preview )

IMPORTANT! watch the instructional video below for the setup and how much TPU to use for the cord.

(*video clarification* You'll tie a knot in the TPU cord on the outside of the slip ring and feed the TPU cord through roarer and the end of the handle, it might be tight to get the double loop of TPU through the center of the bullroarer, if so, wet the tpu or put dish soap on it for lubrication and it will be easy as pie. Remember… you only need to tie ONE knot! :)

Fun for all ages but be safe! Make sure the knot is tightened well and the swinging area is clear! You do NOT want to catch this momma in face…. ouch. ( I did)… I suggest wearing a ball cap when using, just for the off chance you get carried away swinging, the brim of the hat will protect you from slapping yourself in the noodle too hard :).

ProTip! – You don't have to rotate very fast to get it spinning and loud!
