Replacement peg for the shelf in my closet. The peg is inserted with its side pin to the closet's wall, then the shelf is lowered onto it from the above, and vertical holes drilled in the sides of the shelf are put on the peg's main body.

Printed this in PETG, laying on the side (part of the peg went "below the bed level" and hence was missing). That way the position of layers is the best for peg strength and to avoid breakage.
You can use supports to avoid losing part of the peg when printing in the same position.
