Banned within the United Federation of Planets, only five Varon-T disruptors were ever produced. Four were held in the private collection of Kivas Fajo until they were confiscated; but you can own the fifth!
(Reproduction of the prop from the Star Trek: The Next Generation episode "The Most Toys".)
Designed in several segments to print cleanly without supports, and for ease of smoothing and painting. Each segment has holes and/or pegs to make alignment easy during assembly.
Segments 1 (end barrel) and 4 (middle barrel) should be painted silver, and segment 3 (square brass rod) should be painted brass (or gold). All the other parts should be painted black.
Once the black paint has dried, the round stud on the back side should be painted silver, and the frame around it should be painted gold, as should the ridged details on the top of the main body (see images for clarification).
Thin strips of Mylar tape should be affixed to the small ridges on the cylindrical features on the side, just to the rear of where the cones join them.
Segments are numbered roughly in the order they should be attached to each other. I used clear epoxy, but feel free to use whatever adhesive you prefer.
There are six "pegs" used for attaching segments 6, 7, and 8; I recommend supergluing them into three double-ended pegs for convenience.
Model was constructed from screenshots, and photographs of castings taken from the original prop. The only dimensions I could find were from the prop's entry in an auction catalog, which listed it as being "approx. 6 inches long". This feels a little small to me, but since they were measuring the actual prop, I have to assume it's accurate.
