Drawings of FW16's battery

Hi hi, I’d like to use framework’s 13 mainboard with the official case for an AR glasses setup and connect it to a FW16’s battery, I already know it’s possible to connect them: Pinout of the 16's 85whr battery?

The problem is I can’t find drawings of the FW16’s battery to design its case before I commit to buying hardware.

I would love to help, but I couldn’t find any CAD drawings just now, and I partly disassembled mine, so the dimensionality might be a bit off vs a factory sample.

Same problem, there’s a Battery folder on FL13 that contains CAD drawings, but no such a thing for the FL16
