Needed replacements after 30+ years. Dirty, worn and messed up with paint. Did not find the right sizes, so I re-engineered them.

Usually you have four parts, maybe five: 

1. Upper (double) cover
2. In between a C-shape cover
3. Lower cover, just slide over from top down
4. Lower hinge link cover ("moeppel")
    
5. In case the window shall not tilt a stop link is in place

Designed in TinkerCad. Most parts have a “one-layer brim” integrated.

Printed in PETG with MK4. Mind how to print, how to orient as they have really thin walls and over stretch in wrong orientation will cause failed parts.
