This is a “wall” for a Rev-A-Shelf under-cabinet pull-out drawer that is designed to prevent lids and/or handles from going outside of the perimeter of the drawer and banging on the cabinets when opening/closing. You can print flat on the print bed for speed or upright with brim for clip strength. I printed upright using silver PLA+ and it matched decently. Included the source file to customize length if needed.
