Lure leader knotter, fly fishing hook winder

This is designed with reference to the Mingbang lure knotter, focusing on low cost and affordability. Because it has threads, the printing layer height can only be 0.12 and 0.08. Note that the circular holes on the base are threaded, but for some reason, complete threads cannot be produced. I used a tap to turn it, and if you don't have one, grind the cylindrical threads, forcefully insert them, and use 502 glue to secure it. If you have a solution, please share it in the comments. This design incorporates collaboration; adjust the size to ensure smooth line release.
After assembly, pass the line through the cylinder, around the winding disc, and several times around the grooves on the disc. Hold it down, then rotate the disc counter-clockwise 1-3 times.

Knotting methods: Search for Mingbang knotter or Gong Lei knotter on Douyin (TikTok). (Personal experience: The wrap must be substantial, at least 1.5cm or longer. When tying the first half-knot, pull it extremely tight. After tightening, it is best to use a lighter to slightly melt the end of the carbon fiber.). The first time you try this, it’s easy to come undone; it took me three tries to figure it out.
This model can also be used as a personal fly fishing hook winder.
