Corner plant shelf support

I just had to place some plants in a corner of a room. Despite there was no piece of wood shaped as a quarter circle, there was not any mounting bracket anywhere available for the shelf. So I had to start my Fusion360.

See pictures how it turned out. For me, it is quite perfect. Carries at least 15 kg planters.
Used 4 screws for the wall and two screws to keep the wooden board in place.

Unfortunately, it took 15h printing time and 241 gr of filament.
I added the fusion360 construction file, so you can edit it. Maybe you want to save some filament or printig time by inserting holes or resize it for bigger/smaller shelfes.
Please post your make (!) or improved remake.

I recommend to set infill to 30% or more of gyro shape. PLA will do, PLA+ will do better.

Finally, give a like to let others know if this is useful.
