Protects the battery from accidentally hitting it (briefly) with the iron and provides a place to put the TS100 when not in use. Comes with a hook to keep the balance connector in place and a built-in XT60 cap.
I've also included a version of the lid without the TS100 supports, if you're just interested in the battery case.
The lid is attached using M3 x 40mm bolts and nuts, although the fit turned out to be tight enough to get away with just using shorter M3 bolts and driving them into the plastic. There is a sacrificial layer built-in just above the space for the hex nuts so that it prints completely without supports, simply cut away that layer if you're going to use 40mm bolts.
The design was made using Fusion 360. The .f3d archive file is included if you want to remix it or tweak the parameters. All major dimensions (including the battery size) are in user parameters (go to Modify - Change Parameters).
