Inspired by a similar thing but for a different variant with a different sized box.

The center type A-to-C cable holder is optional - you can just place the coiled up cable in the same place, the holder just keeps it taught.

Insert dimensions are 114x75x47. The box measures a hair less than this when taken near the corners, but the covering folded over the top lip adds a few tenths and it is ultimately paper and so has plenty of tolerance. Onshape link if you need to alter a dimension – this was a quick sketch and has no variables or documentation, but editing the initial rectangle of Sketch 1 should regenerate most features without too much trouble.
