3 Sizes of very strong shelf brackets

I have constructed a shelf bracket that is 30x30mm thick and designed in such a way that the geometry and the alignment on the printing plate alone provide a very rigid result. I printed it in PA-CF for maximum resilience. In PA-CF I have loaded it with 100kg without it breaking, but I recommend a maximum of 20kg continuous load per angle (not calculated but an estimate). You can print it in all materials that are durable. PLA is not one of them!

Screw size between 3,5 and 5mm are recommended

You can use this shelf bracket to hang very heavily loaded shelves.

It is available in 3 lengths in the print profile so that you can adapt it to your needs. The larger the bracket, the higher the load capacity. The weak point of this construction is not the bracket but the wall. Here you need good screws and wall plugs. The bracket takes 30 mm of screw length. So if you want to screw 15mm into the wall, you need 45mm long screws.

Have fun printing.

I have constructed a holder that is 30x30mm thick and designed in such a way that it already provides a very rigid result through its geometry and alignment on the printing plate. I printed it in PA-CF for maximum load capacity. In PA-CF I have loaded it with 100kg without it breaking.

With this shelf bracket you can hang very heavily loaded shelves.

It is available in 3 lengths in the print profile, so that you can adapt it to your needs. The larger the angle, the higher the load capacity. The weak point of this construction is not the angle but the wall. Here you need good screws and dowels. The angle takes 30 mm of screw length. So if you want to screw 15mm into the wall you need 45mm long screws.

I wish you lots of fun printing.
