Update:Â Now featuring multiple metric sizes, with imperial versions linked below.
This is a replacement 5mm shelf support pin featuring an L-shaped bracket design. Unlike standard cylindrical pegs, the flat bracket distributes the downward force of the shelf over a larger surface area, reducing stress on both the peg and the furniture wall.
Recommended Print Settings To achieve maximum strength and prevent the peg from snapping under shear stress, layer orientation is critical.
Orientation: Print the model upside down with no suppports. Do not print it standing upright. Printing flat forces the continuous filament paths to run lengthwise through the 5mm cylinder, giving it incredible shear strength.
Perimeters (Walls): Set your walls to 4–6. Because the peg has a 5mm diameter, this will essentially force the slicer to print the peg as solid, concentric rings, which is much stronger than using standard infill.
Layer Height: 0.16mm or 0.20mm for a good balance of detail and excellent layer adhesion.
Material: Engineering-grade materials like Nylon, ASA, ABS, or PETG are highly recommended to prevent the plastic from creeping under continuous load. Nylon is particularly recommended for its durability. ASA prints beautifully for this application, especially if you are using an enclosed, high-temperature setup.
