This hoodie bead in the shape of a skull can be easily placed on your hoodie cord. A spring inside holds it in its place. The skulls should be printed upside down (no supports needed) and with a brim. Springs should be printed on their sides. Satin or matt PLA is not recommended for the springs because of the fragility of this filament type. The spring should be inserted from the top of the bed until it clicks into a groove. The beads in the photo were printed with a 115% scaling
