The prompt
Create a high-precision, vertical 3D engineering assembly model of a futuristic intermediate ammunition cartridge with a total overall length of 57.4mm. The assembly must feature five separate, proportional layers based on real-world dimensions: 1) A base-level cylindrical metallic cap measuring 9.6mm in diameter with a tight 1.1mm deep physical extraction groove. 2) A main hollow outer casing wall measuring 36.6mm in length, matching a standard 5.56mm magazine footprint, made of a smooth material. 3) A solid, dense internal block matrix filling the interior chamber of the casing wall. 4) A front neck section holding a 5.7mm diameter segmented sleeve carrier split into vertical thirds. 5) A long, razor-sharp central needle dart core protruding straight up from the center of the sleeve carrier, with a thin projectile diameter of 5.0mm. Ensure the entire model is oriented vertically, perfectly aligned along a single center axis, with clean boundaries separating the internal block from the outer shell.
