Not sure what you mean by 944II? But if it's a US spec '86 944 or 944 turbo, there's a very high chance you need the 20x21 gear posted above. To confirm, count the number of teeth of the gear it meshes with. If that gear has 49 teeth, you need the 20x21 gear. If it has 48 teeth, you need the 20x22 gear.gezso wrote: Tue Mar 18, 2025 3:58 am Hi,

Thanks for this feedback. When I printed mine it was in a super strong glass fiber resin. Did you print on a regular FDM printer? Can I ask what printer and material you used?jrbennett wrote: Fri Apr 25, 2025 8:48 pm Printed this gear and installed the other day, just over 50 miles so far with no issue.
Thanks for sharing the file, now I just need to find the sunroof guide.
I teach in a high school automotives/mechanics class, I had our design/technology teacher print it for me, I'll get the printer and material info from him and updateTom wrote: Sat Apr 26, 2025 7:15 am Thanks for this feedback.

Wow, lucky kids working on Porsches in high school! I had a high school automotive class, and we worked all year to get the motor in an old jalopy running. I think it was a 383 Chrysler if memory serves.
That original gear doesn't look bad? Just make sure the printed one is not made of PLA plastic. PLA will not hold up in the summer when the car gets warm inside. PLA parts left in cars will start to droop and deform. PETG would be the minimum, with ABS being better and a glass or fiber-filled PETG or ABS better still.

The original gear does not look bad, although all the smaller teeth have actually fallen off. The 3D printed gear installed was printed with PLA, I've since printed an ABS one but first we'll see how long the PLA lasts. So far 263 miles.Tom wrote: Sun Apr 27, 2025 5:23 pm Wow, lucky kids working on Porsches in high school!

We have several older domestic engines in the school, mainly inline 6 and V8 push rod engines, even a flat head Ford, although most of the hands on work is heavily influenced by my collection, primarily air-cooled VWs.
