Winder

This is a winder we use for retrieval lines for our radio controlled yacht racing marks. In this case these are loaded with 75m of 2mm polyester line.
Printed at 30% infill except for knob components at 100% infill.
Additional items required:
8mm X 90mm Stainless steel Hex head bolt and Nyloc nut plus 3 washers.
4mm X 40mm Stainless Steel Pan head or flat head bolt and nut.
2 Skateboard bearings 22 X 8 X 7mm - I couldn't find S/S so oil them once a month and a year later they are still fine.
