It looks nice. I like the way you integrated the cabinet handles.
I’ve been using “press-in” rubber feet to protect surfaces and prevent slipping. They have a lower profile than the stick-on versions and seem to stay put better. I don’t remember where I got them. Very low profile so does not appear to have the items floating above the surface.
I drill a 5 mm hole and simply press in the feet. Highly recommended. I also use bump-on self-stick for situations where there is no horizontal movement to shear the bumpers off the surface. But for a tray bottom, press-in. Much lower profile than screw on and just as durable.
Lots to choose from:
