Heavy-Duty Customizable Shelf Bracket
A strong, highly practical, and customizable shelf bracket designed for easy mounting and maximum strength.
Features
Easy to Mount:
All mounting holes are completely accessible—no diagonal brace blocking your screwdriver or drill!
After installation of the Bracket onto the wall you can simply slide in the Corner Brace from the side or "open" the Bracket itself a little.
The Corner brace has "noses" to stay in place. Once there is load onto the bracket it "locks into place" and won't "fall out" by accident.
Strong:
Tested up to 84 kg (my body weight) using PETG and with the installed corner brace.
Customizable Design:
Play with colors to match your space.
Customize the look of the Corner Brace! Print it with solid walls or expose the infill for a striking geometric look (e.g., 2D Honeycomb at 15% infill).
Slicer settings: Set Bottom and Top Surface layers to 0.
Note: The structural strength depends partially on your chosen infill pattern and density.
-> If I reduce the infill percentage I also like to thicken the infill itself as showed in the picture below.
Otpional future elements: The Corner Brace could easily be redesigned for other shapes.
"Corner Plug"
You can add a Corner Plug as an additional and optional design element to hide the screws :) Simply "press it" into place or use the version with magnets.
Scalable:
Need a custom size? Scale all parts uniformly in your slicer.
Keep in mind that scaling changes the screw hole diameters, so you may need different hardware.
Material Recommendation
Choose a tough, rigid material capable of supporting continuous load over time.
Recommended: PETG, PCTG, or ABS/ASA (especially for heavy shelves or humid environments).
My Choice: PETG.
