Shelf bracket with extensions

Just a shelf bracket with extensions, yo can add a safety extension (included an example), as well as add stuff using the connectors, a twin (rotation free) hooks example is included as well.

It was designed just by logic, I added some kind of T channels on the sides to, I guess, make it more resistant

In the future you can design an extension to get hanged there, for that, I've included some crossing "bars" to this T channels to have some fix supports along it.

Be sure you have a long / thin enough screwdriver before printing, I've designed it to fit my tools while being as resistant as possible, one more time, just by logic.
