Modeled in Blender and edited for printing.
Pretty simple to construct:
Print a Top, Mid, Bot, Shroud, and Knobs (2)
I've included the larger parts broken up to print on smaller printers as well as larger parts.
I can print one of these in less than two hours by spreading across 5 Dremel 3D40's - that's the one in the cover image. Can also be painted and weathered.
It really wasn't an attempt to go 100% movie accurate and shouldn't be used as such. I didn't do the design in proper CAD so some of the faces are wonky from the subtraction I used to make the parts printable. Everything should be manifold and I have no issues running it through Simplify3D
Support on the bottom section needs to be carefully removed using tweezers. There's room to get the supports out.
Print everything vertically.
