KSP Style Ecig holder

loosely based on my favorite Space game mun lander. This will hold your Ecig with no fear of falling over and with space for 3 spare batteries you wont be caught short. Jeb would be proud..
holder large = 1x23.2mm 3x19.2
holder small = 1x23.2
NB: don't print it in conductive material ok !
