Patio cup/mug holder

I tried to keep the design somewhat interesting by adding curves and so on. This mean that the best way to print it is really on its mounting surface.
I used 2 #10 screws and screwed it in by hand to make sure i don't over do it.
Also I painted the surface to make it last longer to UV.

PS: One of them failed due to printer overheating, so i had to measure and print the remainder and then glue it. Can't really tell. Feels really solid and I might have overdone it with the thicknesses.
