3D printed exhaust port covers
 

Hey guys,
I recently picked up a spare 305E. The exhaust manifolds were removed leaving only an open port. Instead of having them exposed to all the nastiest of my garage, I decided to make 3D printed exhaust port covers. This is my first real attempt to create anything in OpenSCAD from scratch. They are probably a little over built but all in all I'm happy with the way they turned out.
The 3D printer .stl file is in the attached zip archive.
Hope someone finds these useful
Enjoy
Chuck

Nice. Simple but effective. Cleanliness is next to godliness when it comes to engines!

I was installing those covers and came across a broken exhaust bolt. It was broken off flush so I decided to drill it, no biggie I've removed tons of broken bolts. Of course it won't budge and I used a little too much force breaking the easy out. Wound up having to resort to other tactics to get that out of my way. Hosed it down with PB and will wait for a day above freezing to decide weather to continue to drill or weld a nut on it. LOL

It's good to keep your skills up while you are learning new ones.

Nice job. A little ceramic grease on those exhaust manifold bolts saves a lot of frustration and grief when you have to remove them down the road. Of course that's easy to say if you didn't put the engine together years ago.
