Replacing O-rings

Does anyone have experience using metal extension springs to replace the actuator’s elastic o-rings? I am thinking to try something like this

We have generally steered away from springs as they are very hard to spec reliably for distributed manufacturing. But it would be exciting to see a version with springs working!

It has been a while since this post. This issue has been lingering in my head for quite a while. But here it is…a metal spring loaded OFM. It was a challenge to hook the loop end inside the microscope. It works great so far. I havent had a problem for over 6 months now. I changed 3 sets of o-rings to the other microscope in the same time. GO SPRINGS!
