This bracket can be used to mount an IVAR "side unit" (e.g. https://www.ikea.com/us/en/p/ivar-side-unit-63756709/) to a wall or other furniture.
The pegs allow it to support the IVAR without drilling holes in those precious pine pillars.
It provides some spacing away from the wall, about 16mm.
Print with supports ("everywhere") for the pegs.
