I am considering doing something similar, but instead of rubber bands, did you try doing it using just counterweights ?

If you need some elasticity, maybe the counterweights could be attached using a spring ?

Does it make sense ?

Totally!

The rubber band solution was working great at the beginning, but they wore out over time, so I upgraded to the counterweight solution.

A plastic coated metal string is running over two ball bearing down to a moving weight.

The extruder is now really "flying" - negligible force influences to the end effector no matter at what position!

(In comparison to the "very new" Fly-n-Strude.)

Yes, it is. Get it above 40deg Celsius now.

It looks a little bit like a plant growing box.
