The prompt
Generate a 3D STEP and STL engineering file for a custom miniature inline-4 intake manifold to adapt four individual CISON L4 model carburetors onto a Toyan I4 engine block. The design must feature a single 3mm thick cylinder head base flange. From the flange, create 4 completely independent, separate intake runners with no shared plenum log. Each runner must have an internal bore diameter of 6mm. The carburetor-mounting end of each runner must terminate in a circular 10mm outer-diameter slip-fit sleeve. Space the runners with a center-to-center clearance of at least 26mm to prevent the carburetor bodies from touching. Optimize the geometry for 3D printing with SLA resin or SLS nylon, maintaining a uniform 2mm wall thickness."
