Description

This is a cold air intake system for any car that has a wide but narrow (top to bottom) area to pull air into the engine compartment. This one is for a Porsche 928. These three parts are designed to print on a Prusa Mendel vs (hence the corners cut at a 45). You have to put each piece on the bed at a 45 degree angle (rotate 45 in the z-axis and then click 'center object' in Slic3r). I haven't printed the scoopfront6.stl so I'm not sure it will work OK (My mendel has interference issues at the top of the envelope on one side because it hits the frame). So that part is a work in progress, but the other two pieces came out good. Here's the way it's set up from back to front: Scoop3b.stl is the part inside the engine compartment, it connects to a 4"ID flex hose going back to the MAF.
