I bought a battery from iFixit but they just give you the tools in a plastic bag, so I designed this little box to fit all the screwdrivers and opening tools that came in the kit :)

The long section holds screwdrivers, spudgers, tweezers, pens, stuff like that.

The short section holds the suction cup and the little opening picks.

The sleeve fits pretty tight over the tray, so you can use the looser print profile if you want that.
