Sturdy 3D-printable angle brackets for shelves, boxes, frames, furniture repairs and all kinds of workshop builds.
Every bracket has a reinforcing corner gusset to stop the legs from flexing, and countersunk holes so the screw heads sit flush.

Why I made it
I kept needing small brackets for quick fixes and projects, and store-bought ones never came in the right size. So I made a full set that prints fast and holds well.
