I Bought these Chairs not to long ago and they already start falling apart. So I thought I might replace the feet with some proper ones.
Some they do not break after 3 Month of using.
As always it might depend on your printer but I print at least 5 shells.
-----UPDATE-----
Print it in Flex Filament with at least Shore- 60D.
Do not make the same mistake as I did and print it in PLA.
It will scratch your floor.
