Hello,
This is a brake duct that can easily be printed and installed to replace your long-lost or beat-up brake duct in your E36
BMW. Part numbers:
Left (Driver) - Genuine BMW # 51712233361
Right (Passenger) - Genuine BMW # 51712233362
It must be two parts to fit in the MK3s+ build volume. I included a file of the full brake duct as well for you Prusa XL pre-orderers out there. I assembled them with some super glue that has held up just fine. It fits quite well, but some drilled holes and zip ties will ensure the brake duct doesn't make a “break” for it ;). I drilled some holes and zip-tied the ambient temperature sensor for the car into the duct as well. There are 3mf files as well as the SolidWorks versions so you can modify them. Sorry, the sketches are undefined, it was a quick turnaround job. However, it works the way it is now or can be polished up and improved in the future.
Thanks for looking and let me know if you have any questions or if I can make any changes.
