Accessories for a rolling metal tool cart, like the one sold at Harbor Freight. Accessories include, hooks to hold a small trash can under its lip, (and a clip mount a stopping bar made with PVC to rest it against), a paper towel holder, (also uses a small piece of PVC and a screw washer and bolt), a rubber glove box holder, holder for spray cans, and a cup holder with cut out for coffee mug handles.
UPDATE: I added a new version of the paper towel holder (version 2 in the files) that mounts below the handle. I also added a bar to stop the wind unwinding the roll of towel. This version also makes room for all the other accessories to be on the same side of the cart narrowing the overall width.
