Customizable L-Bracket 90° Shelf Mounting Bracket

Whether you're hanging a heavy-duty garage shelf or just need a perfectly sized bracket for a custom project, this Fully Parametric 90° L-Bracket is designed to adapt to your exact needs.

Instead of hunting for the right size at the hardware store, you can customize every dimension of this bracket—including width, length, thickness, and hole placement—right here on MakerWorld.

⚙️ Key Features:

• 100% Customizable: Easily adjust the height, depth, and width using the parametric customizer.
• Engineered for Strength: Features customizable concave ribs to maximize load-bearing capacity without wasting filament.
• Dynamic Hole Placement: The script automatically calculates and spaces your screw holes perfectly based on the size of the bracket you generate.
• Clean Aesthetics: Includes adjustable fillets (rounded edges) for a professional, finished look that won't snag on hands or cables.
• Hardware Matched: Dial in your exact screw hole diameter and countersink depth so your hardware sits perfectly flush.

🛠️ How to Customize: Simply open this model in the MakerWorld Customizer! You can tweak the sliders to fit your exact shelf depth and screw sizes. Generate the model, and it's ready to print.
