Yarn Spinner with stronger spindle peg

I split the peg in half lengthwise and printed the halves separately to make it stronger.

I love this yarn spinner design but found that the spindle peg was a weak point - over time it would weaken and snap in half on me at the junction between the spindle and the base.  I think it'll be much stronger if it's printed lengthwise so I split it in half lengthwise and print each half with the flat side on the print bed.  Also, this way no supports are needed.  To assemble, just hold the 2 spindle peg halves together while you press fit as in the original design.

I also print the peg in TPU since I thought that might be less brittle and provide some give.  I think PLA would work and still be stronger than the original, though.

Print Settings:

  • Material:  TPU (I used 98A) or PLA for spindle peg, PLA for base and spindle
  • 0.4 mm nozzle
  • 0.2 mm layer height
  • 15% infill

Same instructions as in the original design:

Required Materials:
608 bearing (preferably one without lubrication)

Assembly:
Press-fit the 608 bearing into the base. Press-fit the spindle peg into the bottom of the spindle. Press-fit the spindle assembly into the inside of the 608 bearing. This was designed to be held together with friction, but if needed you can add some CA glue to loose parts.

Model origin

The author remixed this model.

Differences of the remix compared to the original

Split the spindle peg in half lengthwise and print both halves with the flat sides on the print bed.  This results in a stronger peg and no supports are needed.  Also, added fillet to the spindle base to reenforce it as done in DigsHistory's remix.
