Here, I mostly fixed it. I am sure I wasted my time, but maybe it will keep someone from making these mistakes.
The control panel is at too steep of an angle. People are still going to set drinks on it at that angle but they will get knocked over. Better to be closer to flat and it won't happen. I didn't bother to change the angle in the picture, too much work.
That little curve at the front of the panel does nothing but create a weak point, exaggerate the lever effect, and keep the players away from the controls, so off it went (also, real cabinets never really did that until very recently when Chinese companies started doing it, but they were literally just copying the bad designs from here).
Front of the cabinet comes out near the front of the panel. This makes the cabinet stable and strong. For maximum strength that front panel should only barely be recessed from the sides, cabinets that recessed that panel 2 or 3 inches were always getting the front corners knocked off them (see most unrestored Robotron cabinets).
Also, that complex panel shape you have going there just makes your machine more difficult to build, weaker, and creates some nice corners to poke your players in the stomach. See basically every real 4 player cabinet ever to see how they all had rectangular panels. Finally your panel seems to be at least 4-6" needlessly too wide for the control layout you show, even if you keep the spacing as is. You don't need 6" of empty space between a control and the cabinet edge, 1" is fine, almost touching the edge of the box is fine.
