XCargo Topper Bit
This tool allows you to use a cordless screwdriver to tighten the finger nuts for a cargo topper. You'll need a 1/4 inch hexagonal driver bit - I had to tap it in with a hammer the first time. See pic.
If you have time, try to remove some of the excess plastic chunks to speed up the print.
