Super Short Sides for Stackable Case

I didn't plan on keeping batteries in my stackable case, so I wanted something that would keep the drones from bouncing around. I've shortened the case sides to fit my Mobula7 1S and my Moblite7 Walksnail.

Printed with PETG at 0.28mm layer height on my Ender 3 Pro. I didn't use supports, and only had a few strings on the first overhang. YMMV.
