Heavy-Duty Corner Shelf Support Bracket

Heavy-Duty Shelf Corner Bracket

A strong and reliable corner bracket designed for supporting shelves in garages, workshops, or any utility space. The reinforced triangular structure provides excellent rigidity and load-bearing performance while remaining easy to print.

The mounting holes are optimized for 3.5 mm and 4 mm screws, with countersunk recesses for a clean, flush fit. This ensures secure installation without protruding screw heads.

Dimensions:

• One side: 40 mm width
• Other sides: 35 × 35 mm

Printed in PETG for durability and slight flexibility, making it ideal for functional use. I personally tested it in a garage setup using standard wood screws, and it holds firmly under load.

Perfect for:

• Garage shelving
• Workshop storage
• DIY projects
• Wall-mounted supports

For best results, print in PETG or another strong material and use high infill for maximum strength.
