TRINITY Shelf Bracket for 2020 Rail – Under-Shelf Storage Support

Create a small shelf under your shelf!

Ideal for:

• Storing long, flat items like golf clubs, skis, umbrellas
• Keeping shelf space clear below

This bracket securely attaches to the wire frame of a TRINITY 5-Tier Heavy Duty Wire Shelf (heavy duty shelf version only, similar to the 60" x 24" Costco version) and supports a 2020 aluminum extrusion underneath. 

Important:

• Designed specifically for the larger or Heavy Duty Trinity model (with thicker top wires)
• Will not fit the smaller Trinity variants or shelves with thinner wire

Materials Required:

• Two lengths of 2020 aluminum extrusion that are the same width as the depth of the shelf. In the case of the 60"x24" shelf shown in the photo, the extrusion would need to be 24 inch (600mm) long. (Amazon)
• 8 M3 T-Nuts (example on Amazon)
• 8 M3x10mm screws (Amazon)
• About  70g of filament

Design Features:

• Securely attaches to the aluminum extrusion using M3 T-Nuts and two M3x10mm screws per bracket
• Fillets along the top hook to match the contour of the upper wire
• Dual hook design evenly distributes the load across the supporting shelf
• Prints cleanly without supports
• Oriented to print for maximum layer line strength

Printing Notes:

• No supports needed
• Use 4 perimeters for strength
• Mirror along the x-axis to produce the left/right pairs for each bracket or use the included .3mf file which has all the parts needed for four bracket sets.
• Recommended material: PETG or ASA (for garage use or heavier loads)
• 0.15mm layer height recommended
