IKEA Shelf Corner Bracket (Part 101558)

This 3D-printed corner bracket is a direct replacement for IKEA part 101558 and sometimes listed as part 10077788 , widely used in the KOMPLEMENT and PAX shelving systems. Designed for a snug fit and durability, it offers an easy way to replace or reinforce your shelf corners.Key Details:Peg Dimensions: Each peg is 5mm in diameter and 14mm long, designed to sit securely in IKEA’s pre-drilled holes for solid support.Screw Compatibility: I’ve tested these brackets with M3 screws that are 18mm in length to expand the peg fully inside the shelf, ensuring a strong hold. However, the original IKEA screws (slightly larger than M3 and around 10mm long) work well with this design, too.Print Angle: For optimal strength, print at the angle provided in the 3MF file to prevent weak spots and improve layer adhesion.This replacement bracket is a practical solution for extending the life of your IKEA shelves or keeping them sturdy under heavier loads.
