The divider measures 390mm long and bows out to a max of 200mm, starting at the foot. The depth of the model is 45mm.

I printed this out in two parts at 0.3 layer height. Divide the model in your slicing software, print it, and superglue the two parts. I would avoid making the model too hollow and use appropriate infill. I used 20%
