Circle cutout Shelf Bracket

thingiverse

I needed some shelf brackets for my home, but everything I saw had sharp edges or didn't have easy access to screw holes, so I got frustrated and made my own. The edges are rounded because our home has textured walls, which should help reduce any obvious imprinting, but it's wide enough to remain stable. After finishing and printing this, I was concerned that it wouldn't be strong, but it seems fine for lighter shelving. I made a stronger bracket immediately after, and you can find it on my profile. The bracket is 4"x4" or 100mm x 100mm, with holes that are roughly 5mm or 1/4 inch - they should work just fine. I haven't done weight tests yet, but I plan to and will update this page when that happens.
