This print requires assembly and glue.
The hole in the Starfleet delta is 0.4 centimeters in diameter.
A recreation of the necklace/pendant worn by Khan Noonien Singh in the movie Star Trek II: The Wrath of Khan. In the film, it is constructed out of a damaged Starfleet belt buckle. He wears it around his neck using a loop made out of wires and other electronic components, salvaged from the SS Botany Bay, his ship, after it crashed on Ceti Alpha V. This recreation is not the exact size of the prop. The pendant is printed in two parts, the broken ring and the delta, and will require glue to assemble.
My example pictured was printed in a shiny coppery PLA at 0.20mm. It used almost 6 grams of filament and took 27 minutes to print. I assembeled it using cyanoacrylate glue (superglue).
Comes as an OBJ, FBX, STL file. Source Blender file included. Included 3MF file was made in PrusaSlicer. I recommend printing in PLA. No supports needed.
