When creating my Death Trooper costume for Hallowe'en, there were a lot of things that I wanted to print but couldn't find. This is one of them. It's a model for the two switches that go on the back of the Death Trooper backpack.

This is not screen accurate, and is sized according to my scaled chest armour in Armorsmith Designer, so you will have to resize it to fit your costume.

Again, this is not screen accurate. It is not meant for 501st or hard-core cosplay, it's just something I made that was close enough for me.
