My own 3d printed design, next to a Hana 200. Measures 105mm x 50 x 24, just 5mm taller than a 1590G box. Would really love to get this made in aluminum. Got a 1200mah lipo pack inside, one could put a smaller cell inside to make room for connectors (XT30, etc) for easy battery swapping. As it is now, there's no wiggle room at all.
