Fishing Spool Winder with 1/4" Hex Shank

Designed for fast and convenient winding of fishing line spools.
It features a 15.5 mm threaded shaft to fit standard spool centers and a 1/4" hex bit shank for direct connection to a drill or electric screwdriver.
An additional nut is included to lock the spool in place during winding, ensuring smooth operation and preventing slippage.

The threaded shaft is a single piece. For easier printing without supports, it is recommended to split the shaft longitudinally in your slicer and add 2x printed dowel pins to align and join the halves after printing. (Bambu Lab 3MF file is already set up this way)

Printing Recommendations:

Material: PLA recommended (easy to print)

Layer Height: ≤ 0.16 mm for better thread definition

Supports: Not required

Assembly: Join the shaft halves with 2x printed dowel pins and press-fit or glue if desired
