A replacement for the E21 chassis moonroof slider. The OEM replacement is about $850 since it comes with other parts. You can't buy it on it's own. Used ones were impossible to find. I made this for a 1981 BMW 320is. This should work with any of the 320's with a moonroof.
I opted to used two M5 nuts instead of heatset inserts. A .step is provided.
This model is specifically the left hand side one. I believe they should be mirrored.
To design this part I used a 2D scanner and a ruler to get a dimensionally accurate image of the part. I based my initial sketch off of the image and key measurements such as the slot width. This allowed me to make a perfect replacement.
