Repairing the end of the chair leg.
After breaking the inner plastic of the kitchen chair, which cannot be purchased, I modeled 3 versions in turn for repair.
file:
Leg - hides the nut inside the body. It is required to stop printing and insert the matrix before continuing printing.
Leg V1 - is designed for a threaded insert that is pressed into the hole when hot.
Leg V2 - is designed for inserting the nut from the side until after printing.
After testing, the Noha V1 proved to be the most effective in my case, which has been in use for about half a year and is still in use.
