Sturdy Bracket for shelves

If you need a sturdy bracket for your shelves, here is a model that should suit you.

And it will cost you much less than at your favorite hardware store !

If you want a version where the screws are hidden by small caps, follow this link: https://makerworld.com/en/models/2835203-sturdy-shelf-bracket-v2-with-screw-covers#profileId-3159843
 

For mounting, I use 50 mm countersunk wood screws. You can choose a different length depending on your mounting surface (wall plugs, wood, etc.). A 5 mm diameter is recommended, but 4 mm screws should also work.

If you need it to be extra strong, use 3 or more walls and use 25% infill or more. I tried 15%, and it’s already strong enough for most applications.

I have posted different sizes. If you ever need specific dimensions, you can use the "Scale" function in Bambu Studio.

 

If you have any suggestions to improve the design, feel free to let me know.

 

For this model, I used PLA but you can use PETG or other type of filament.

A note on print quality: I test all my models before uploading. If your print doesn't turn out well, check your filament (old? wet?) and printer calibration first. Most issues come from these, not the model.
