Just a little 1s 600 Lipo Case

Just a litte case for 1s 600mAh (or maybe others) Lipo case. I designed it for my Graupner Alpha 110 multicopter box. The Lipos will simply secured by a little rubber band.
I'v designed also a tiny holder for my Graupner Alpha 110 in the transport box.
Maybe this is also interesting for you:
