This is a replacement mount for the lift lever to adjust the height and the lever for back angle adjustment.

This should work with most Serta office chairs (I have two different models that the mount works with)

To test whether the mount fits or not just cut the model in your slicer to only the first few layers to see if it lines up with the holes as shown above.

Included as .Step if anyone needs to further change it to fit their chair.

Thanks, and don't forget to post a make!

The more perimeters, the stronger it will be

Supports needed on inside as well as the locking mechanism.
