My kitchen cabinet drawers run on a centrally mounted rail above the drawer. The mount for the rail was a thin piece of plastic that broke one end. I redesigned the piece as a more sturdy mount. I shared it here in case someone else has the same very old cabinets I do. I printed the part our of PC, but my guess would be even PLA would work if you didnt have a lot of weight in the drawer.
