Hull mount case for Pandemonium by Calvin-mcd https://github.com/calvin-mcd/pandemonium
This uses the standard hull-style plates in the pandemonium repo, and your choice of either m2 heatset screws or m3 self tapping screws
Has space for batteries that fit the standard case.
I have only tested it as a FDM 3d print, so use your best judgement for having one manufactured.
plans:
-narrower (no battery) version
-knuckhull -high pro top a la C0V3R
