A lamp for Dummy 13. Or a photon cannon. Or a tachyon beam. Or a particle scanner. Whatever you like best, really. Definitely print with supports (build plate only).
Print the Dummy 13 at 250% scale. If you want to change the scale, you can easily adapt the Openscad file (only the grip needs to be resized). This would probably work well with a slightly smaller figurine, rocket-launcher style, or with a bigger one using it like a flashlight.
I'm combining it with the astronaut mod:

See foto for which lamp type to buy (very cheap on Aliexpress, USB-powered and dimmable, multiple colors, color temps and brightnesses available). Search for “5V USB Mini Spot Led Downlight Dimmable”. You have to remove the spring-loaded clips, then you can just glue in the lamp. Glue all 3 parts together with a clamp as shown. Possibly other (slightly longer) cylindrical lamps with a diameter of 25 mm might work as well, there is a bit of extra space behind the lamp body.
I rendered a version without the decorations, feel free to mod.
