Shelf Stud for Ikea

thingiverse

I replaced a few small metal studs on an Ikea shelving unit with these. They probably work on other brands too, since they're pretty universal. Length: 16mm, Outer Diameter (OD): 5mm, with a ring that's 1mm wide, located halfway down the tube at OD 7.2. They fit perfectly as a replacement for the little metal ones I'd lost.
