before making the entire model, I went to check if the cutaway profile was correct enough to proceed, since I am aiming for it to match current APT-P models on the market.

The idea was to print a small hollowed out section to compare. Here I put a TBF against it to see the profile, and it seems to be slightly taller than what its supposed to be.

Plus, I also realized that the ends of the bottom part of the TBF and the whole bottom section of the NDM is much narrower as you go down. This would also be considered.
