Yet Another PomPom Maker:

• put two arcs together with the screws facing away from each other
• spin yarn on the arcs
• rinse, repeat
• put the two arcs with the yarn together, screw on disc on both sides to keep the yarn from unwinding
• optionally use the clips to hold the halves together
• cut the yarn along the groove on the top of the arc, both sides
• tie all strands together with yarn in the center
• remove screws, free pompom from maker

parts separately as stl-s, or a complete pom maker (one half pom-pom maker :) ) in one file.
