Simple spool rewinder

This highly efficient and straightforward filament spool rewinder is designed for seamless attachment to a drill equipped with a 1/4 inch or larger chuck.The design necessitates only a single 1/4 x 3.5 inch bolt (7mm x 88mm).To operate, simply insert the bolt, ensuring the head is securely seated within the hexagonal cutout. Subsequently, attach the other component by applying gentle pressure and threading it into place. A nut is not required, as the drill chuck provides ample pressure against the spool rewinder. I printed this in regular bamboo lab PLA and had been using it exclusively for some time with no issues.
