3D Printed Car stuff
This is another one of those random pages on 3D printing some parts. All of these parts will be printed in PETG and will be used for my car. Some may find it somewhat interesting of how I design and construct these parts.
Positive Terminal Mount
This part did not come out visually perfect but will work for the application. The battery was located to the rear of my car, the positive bus for the engine bay will be held by this part.
Firewall Wire Bracket
I chose to remove the air conditioning unit so that I could pass some more wires from the engine bay to inside the glove box. A tube from the intake manifold to the MAP sensor on the ECU was the main reason for it. It also passes the wire for the idle control valve and the ground wire from the battery.
Fuse Holder Bracket
I installed a fuse holder for the fuel pump and the main power relay. I needed some kind of bracket to hold it in place.
This grounding terminal is isolated from all of the other grounds around the car as to prevent EMI loops. The grounding system in a car should look very much like a tree with wires branching off, none of these branches should touch.
It is quite amazing how useful a 3D printer can be to make bespoke parts. To make these by hand would take quite a few man hours on machinery. The fact that I can spend 10 minutes designing a part and let the 3D printer run on it's own, and then to return after a few hours to find a perfect part is truly amazing.
