Shelf Support Peg

thingiverse

Fits the Ikea "Billy" bookcase, which has particularly small holes I lost some of the original pegs, so I made a replacement. Print them four at a time, in vertical orientation (such that they are oriented the same way as they will be when inside the bookcase). I recommend adding a sacrificial block on the print bed (to manage heat while printing the very small cross-sectional area of the top of the pegs)
