I made a dial cover for a little Zenith radio a few months back. I used the clear plastic from a birthday cake package and made a mold from some masonite. I cut out the shape of the dial cover with a knife and sanded the cutout piece to allow clearance for the plastic between it and the outer piece of masonite. I warmed the oven up on its lowest temperature (something like 200 degrees) and laid a piece of the plastic over the inner piece inside the oven. I bumped up the temperature until I saw the plastic start to droop then I pulled the plastic out and pushed the outer portion of the mold over the plastic and held it together with some weight until it cooled. It turned out pretty good although the size could be adjusted a little bit. One thing that I noticed is the plastic did shrink a little and clouded up when it got to the temperature where it drooped. The cloudiness went away and the plastic became a little thicker than it was before being heated.

BTW, that is asbestos in the bottom of your cabinet. You can either wet it down and remove it or spray it to contain it and leave it there.
