I'm living in rentals and need a way to mount floating shelves without damaging the walls or losing my deposit. I've invented a DIY solution using nails driven at a 45-degree angle into the drywall, much like a picture hook. My aim is to make the installation quick and easy—under a minute, ideally! So far, it's holding lightweight items (under 5kg), but I noticed that the metal bracket starts bending rather than the nails pulling out. I'm currently working on a new prototype with thicker metal to support heavier items like books. I'd love to get your feedback and any tips to improve my design! Have any of you tried something similar?

You might want to rethink that top angled metal bracket. Instead, try placing the nail through a hole on the flat back piece. A flat back will help keep the force directed downward, minimizing any outward pressure. If you want to hide those nails, maybe a trim piece attached with magnets could work, so flex isn't a concern. Just remember, if things go wrong, your shelf failure could be a bigger headache than just a hole in the wall!
That first prototype bracket looks interesting! I suggest you consider adding gussets to the sides for extra support. It could really help stabilize the whole setup.

Thanks for your thoughts! I see what you're saying about the 45-degree angle—it's similar to the way picture hangers work. Could you clarify what you mean about the trim piece with magnets? The bracket will be concealed since the shelf slides over it, making it invisible.
