This is a specific implementation to qualify for the Replacement Parts competition.
This implementation of the endless endcaps fixes the Ikea Sune Bar stool (AA-321913-1).
I picked this chair up from the side walk, it was probably thrown out because of the broken / missing endcap. It was not very stable, so I had to create a replacement part.
The part should be printed as the stl file imports, the closed end on the bottom.
This is an easy no-support print and will bring new life to a thrown away item.
Check out the endless endcaps entry that explains how you can use the scad file to print out an endless variety of endcaps.
The author marked this model as their own original creation.
