I've Hacked and slashed the bellows frames for quick printing to test bellow fit for My Custom Bellows Upload, which is printed in TPU and in Vase Mode.
This would help when printing in a different nozzle diameter or extrusion width.
Cut the top and bottom off my bellows model when you have made modifications and print them to check the tolerances are right before printing the whole Bellows. Just don't forget to customize the height.

Fusion 360 .f3d files included. The dimensions for my V2 file should be right for this original camera model, but you may have to tweak the width and length for your extrusion width for tolerances depending on your nozzle diameter.
The author remixed this model.
