The detonator started as a file from thingiverse.
I made some modifications and added the inevitable lights (lol).
Fortunately I own one of the original props from the move, so I made a picture of the radio scale, resized it and printed it to fit the model.
Some UV clear was added to give the impression of glass.
Upon inspecting the pictures, I could have sanded a little more, since there are printlines visible and I hate that 😉
