Endcap for AllSteel vintage office chairs

thingiverse

This is a replacement for the plastic endcaps on my AllSteel office chair from the 70s. It is modeled after an original endcap and fits very snugly so it should never fall out. Print at 0.2mm layer height or finer for best results. I drafted a test print with 0.3mm layer height and the fillets didnt show very well. You will need to use something like a rubber mallet or a screwdriver handle to tap the endcaps into the metal railing because its a pretty tight fit. If the fit it too tight, you can try scaling the piece down in your slicer by maybe 1 or 2% if necessary. I used PLA for this but any material should work fine.
