Compact UR65 US65 UK65 case | power whoop case

The UR/US/UK65 is a great compact brushless whoop, but I couldn't find a case that would be equally compact and, at the same time, be able to hold all 6 batteries (capacity of the default charger).
It is my first design, but I think it came out well. Designed in Fusion 360, after attempting to design it in 3D Builder and Vectary. I'm enclosing the .f3d archive file if anyone wants to do some changes under the CC BY-NC-SA license.

I am also enclosing the battery holder .stl, if you want to print that first to make sure your batteries will fit. Mine fit even when little puffy ;)
