The file 'Harbor Freight 19″ Toolbox Tray Insert 3D Printer Model' is (stl) file type, size is 57.6KB.
I got tired of parts falling from the top tray into the bottom section of my Harbor Freight 19" toolbox, so I printed an insert that snaps in place to cover the hole under the handle. No glue or fasteners and it stays put. I used organic supports for the two side tabs and they came off cleanly without clogging the channel.
It takes a bit of fiddling to get the insert into the tray opening, but it does fit. You can no longer grab the tray handle full-fisted, but it's still easy to pick up and manipulate the tray.
