This is a reimagining of the classic Silver Bullet yoyo as a fixed axle. Show here 3d printed in Prusament Linden Tree wood filament.
It uses a 4mm x 20mm stainless steel shelf pin as the axle. These are the ones I used. https://www.amazon.com/gp/product/B0D1VF3P4C I recommend a tiny drop of super glue in the axle hole then the pin, then the other half with glue as well. Print this one at 100% infill.
The six shooter holes act as the response to make this one go back up.
The author marked this model as their own original creation.
