Floating system

Update-2: printed a prototype just for a very little test and I realized one problem in the design which I corrected with _V2 files. Not perfect but funny :-) Update-1: uploaded stl files for 3d printing. Now all parts are independent and you have to mount the system. No glue neccesary. (All _V2 are the last version of the model) See pictures for better understanding. The glass/bottle with liquid acts as a counterweight, balancing the system. The glass/bottle remains fixed with a net which adapts to any shape. Meal and drink go at the same crutch for a good balance and because you can use the other hand to manage the dish and the bottle/glass. Should be nice a fast clip between the Floating System and the crutch, as by now I use screws. The top of the part where you put the dish must be covered with a rubber/silicone sheet to keep the dish in place.
