Any Size Parametric 90 Degree Shelf Bracket / Corner Bracket. Imperial & metric!

Boost Me If you like my model, I would appreciate it if you could click on 'Boost Me'

This is a simple yet versatile parametric 90 degree bracket. This bracket can be re-sized for virtually any need via the OpenSCAD parameters. The bracket can also be set to 3 different styles; Normal Bevel, Low Poly, and Extra Low Poly.

I have pre-generated STLs for a set of imperial sizes from 1x1 to 8x8 inches that use #4, #6, or #8 screws. See the table below for the sizes and screw placements/measurements.

If you want to create a custom size, I have uploaded the OpenSCAD file that you can use to change the parameters. You can modify the height, length, width, screw hole placement and size, screw head size, and poly style, and more. I have also uploaded the .json file(as a txt file in the documentation section) that contains the settings for the pre-generated STLs listed below.

NOTE: The OpenSCAD file is not perfect :-/ Sorry, but it take too much time to be perfect. If you make a setting too big or too small you might get something that doesn't even look like a bracket. However, you can use the settings in the .json( 90DegreeBracket.txt ) file as a starting point. I needed to upload this as a txt file, so to use it, you'll need to rename it to 90DegreeBracket.json if you want the “Parameters” tab to display in OpenSCAD (or just look at it and use MakerWorld's built in customizer).

NOTE #2: Yes, I know the normal bevel style takes a looooooonnnnnnnggg time to render(like 5 minute sometimes) :-(. Sadly OpenSCAD has some mesh issues sometimes, so I needed to use a very large polygon count to get everything to line up correctly :-/. I'll try to fix the rendering time later after I make a few other enhancements.

Printing

I recommend printing these flat with a few paint on supports inside the screw access slot in the angle support. See images for an example.

Otherwise, use your discretion on fill and perimeters depending on how strong you need them to be.
