Boro Mech Mod

I want to make a mechanical mod that fits standard boros powered by an 18650. This is a first draft that I have not printed. I plan to use hardware from a broken SXK billet and some silver contacts from an old squonk mod. This is my first go at CAD so if you print this and get it working, let me know. I'll update this design as I add doors and maybe some texture on the outside so it isn't so bland.
