Setup printer to make the part as solid as possible, as your kids will be rocking back on the chair (thats how the originals all broke right?) On UP! printing with surface=6 layers, and finest fill, and 0.3mm

Take a bit of care cleaning the support out of the ball socket part. Feet are a little longer than originals, so replace them in pairs to keep the chair level.

New Rev1C:

  • puts 5 degree tilt on the bottom of the sleeve part to allow for the legs angle a bit.
  • So, There is a small orientation tit on higher edge to help when fitting to leg
  • Edge of foot is now rounded Visualise variable switches parts between printing and visualising placement.
