> Remix of @Murphy360's version. Removed French cleat attachment and moved the hangars farther apart to accommodate the new wider lithium ion packs.  Also expanded the hanger itself by approx 1mm in X and Y, as the newer packs were just a bit too snug in the holder(old packs fit perfectly fine).  Batteries do not latch in, intended to be mounted on the wall.Printed with PLA but PETG or ABS would work just as well I expect.Layer Height:  .28mm (will print at lower heights, I just didn't want to wait the extra print time and its going in the garage so...)Line Width:      .44mmInfill:                 20% Gyroid for strength, but probably overkillMaterial:           PLASupports:         No
