Fallout Small Energy Cell Replica

This is a replica of the Small energy cell Ammunition for the Laser pistol in fallout 3/ Fallout new Vegas. I’ve made two versions of this; one is fully printed and accurate to the game files but with a far higher detail level. The other was designed when I noticed that the cells in the item are almost exactly the same size as AA batteries and is designed to accommodate three of them making an actually functional cell (I’m actually thinking of designing a battery compartment to fit these, it should be trivial)
I’ll put up a better pic as soon as I receive the grey filament I’ve ordered.
