This is a 3 part bracket that fits onto the Ikea BROR shelving system attachment points. 4 of these brackets provide arms with which to fasten custom shelves to the BROR shelving rack.

Each of the bracket pieces attaches to one of the BROR fastener points, and the arm piece dovetails in to keep everything secure.

Designed with 0.05mm of clearance for the dovetail fitment. If your printer cannot do 0.05mm of tolerance or better you may have fit problems.

Print the brackets with the "keyholes" face down on the plate for optimal strength. The overhangs need no support. Print the arm with the top surface face down on the plate.
