Mushroom Shelves for IKEA SKÅDIS pegboards, 40–200% scale.

Assembly: Put some CA glue (super glue) in the holes and insert the pegs. I recommend gel super glue. 

40, 60, and 80% scale use a single peg, so they're decorative only. Use “peg_short” for these.

100–200% scale use two pegs, and can support some weight! Use “peg_long”.
