Harbor Freight 19" toolbox tray insert

I got tired of parts falling from the top tray into the bottom section of my [Harbor Freight 19" toolbox](https://www.harborfreight.com/tool-storage-organization/tool-boxes-bags-belts/19-inch-toolbox-with-top-compartment-66491.html), 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.
