Nate,

Did you receive a sample of this for a reverse engineered 3D print?

I have one I could send, but the fine edge broke and I superglued it back on.

Vendors already complain enough for getting ripping off by others copying their products. Are you sure you want to do this?

He's talking about copying the stock part that breaks, who exactly is he ripping off?

GT6ixer

Exactly. I'm not looking to reverse engineer an aftermarket replacement cover. This would be an option for those that want to mend their stock part. If it works well I'd make the CAD file available on Thingiverse for anybody with access to a 3D printer to build themselves.

When Porsche installed the original sensor they pulled it back firmly into the dash to make a dimple recess, then tie wrapped it. This put the stress on the face which broke the edges. Before Jager created his covers I replaced the entire sensor, but just drew it flush with the dash surface. It's been many years and my replacement is still intact where the original didn't last 10 years.

Pics of air temp sensor guts for posterity. This is from a '91.

Sorry I misunderstood it. Thought you wanted to make copies of the Jager cover.

You are going to be able to make a precision piece like this with a printer? I've seen a few printed parts done by DIYers before and they all looked pretty sloppy.

GT6ixer

Yeah I agree. All depends on the printer they are using. Those you've probably seen are using FDM (filament deposition modeling) printers. Essentially they melt thin filaments of plastic, like ABS, to build up the part layer by layer. This creates visible ridges and rounded instead of sharp edges. And the layer resolution is typically .1mm. I have access to a polyjet printer at work. The resolution is about 40 times sharper with layer heights of only 28 microns. The parts are pretty much flawless.

We already tried making the cover with a 3D printer and the results were not acceptable.
As far as copying is concerned the part is an original Porsche part copied by jageng in this case.
Anyone else going to the same trouble is fair game in my book. Unless they have a patent on it which I doubt very much. I have sent hundreds of customers to jageng but the shipping is slow and I make nothing.

We have now used the original part to create a cast and we are in the process of making a mold to produce the part economically. As the part is originally a textured black we plan to reproduce an identical part that will fit over the offending original.

Mark Anderson

When you're done can you please send me one to copy?

GT6ixer

What was the make and model of the printer you used? Why were the results unacceptable?

Many people think the DIY printers you can buy is what 3D printers are. They are fun toys but what we use in industry are a far cry from what I assume you had your part made on. I will send you a sample of the part I am going to make with my printer. You'll be impressed.

Also I am not planning on making a cover, which as I understand was never a Porsche part. I plan on making a replacement for bezel inlet for the sensor. This piece is not shown in the PET as an individual part. I assume it is part of the sensor assembly and Porsche never offered it by itself.

A 3D printed cover on the other hand would be even easier to make. Plus it could be customizable in its look.

The Forgotten On

Will anyone ever recreate the weird early 80-81 assembly that has the fan motor and sensor all in the sensor body the size of the later ones?

A few of us have consoles that will not accept the later style sensor/motor combo because it lacks the mounts.

Nate - I am not a 3D expert but these were made by a professional organisation that specializes in 3D manufacture.

I had the same issue with the bumper plugs - surface finish was not smooth and no matter what material they tried it just cracked when pushing the plug into the bumper. We went with the cast and mold method and the part was totally successful. Tooling costs are higher but well worth the $.

ROG100

Care to elaborate as all the sensors were the same from 80+. Part number 928 624 041 00.
What am I missing?
