Nomad from Star Trek. The interior has been set up to receive electronics. Hollowed from the base all the way to the top. The blaster area at the top has been hollowed as well so a bright white light can be added. Fitted windows made to go in to those holes. The head area and probes are set to receive telescoping aluminum. I used K&S #3403 from Amazon. Depending on your shrinkage when cooling these may be very tight so have a hand drill ready in case. Support is recommended. I printed mine at 150%. It was just over 1/2 of the actual prop size.
