Functional Bed Shelf - including cupholder

Here is my first design in fusion to solve a problem we had at home - my sons bed is a mid sleeper bed and he needed somewhere to put his drinks/remote etc... and all the shelves I could find were flat shelves where drinks would surely be spilt and items dropped. This shelf is suitable for a 1 inch deep side of the bed with a large overhang. Please be kind - I will make improvements - the print didnt come out great for his one - I used Black PLA as had run out of the white I had wanted to use.
