Your 3D print model is excellent – it really helps us a lot and saves both time and resources in our work. Thanks for sharing it!
The instructions for replacing the part are also very clear and well done.
I wanted to ask if you might also have a 3d model for the outer latch, the one you have to use to open the carriage ?
That would be incredibly helpful for us as well.
