Majacraft spinning wheel bobbins

These bobbins are designed to be used with Majacraft spinning wheels.

They come in three four different variants:

• Lace (disc diameter 75 mm)
• Standard (disc diameter 87 mm)
• Jumbo (disc diameter 120 mm)
• Standard with WooLee Winder gear (disc diameter 87 mm)

Each bobbin consists of three parts: two discs and a tube. The parts are screwed together using M16x1.5 threads integrated in the model to avoid having to glue them together.

Tubes come in two variants:

• "WW_Tube.stl" for WooLee Winder bobbin
• “Tube_nonWW.stl” for all other bobbins

The discs

• Support: yes
  • Both discs can be printed with the inner surface on the bed for minimal support
  • There is a small gap between the print bed and the start of the thread; support material helps to not print in-air

  • the non-WooLee Winder tube has some support integrated into the model that you must break away after printing
• Infill: 100%

Post-Printing

1. The tube itself is mostly hollow, but the two holes for the flyer shaft are designed to be narrower than necessary and must be drilled open using a 8.0 mm drill. After than use a bit of type 600 sand paper to smoothen out the inner surface of the drilled hole.
2. If the discs wobble, please make sure that all support material is removed and that the discs are screwed tighly onto the tube.
