Are Model F springs the same as a Model M? I bought a few extras with my keyboard and putting it up next to a Model M they atleast look almost identical.… can someone confirm if these springs are interchangeable and if they are the same? And if they are different; what exactly makes them different? In terms of “feel” the model F feels way more consistent compared to the Model M so it makes me want to maybe order a bunch of of springs to try them out on the Model M to see if it makes the entire keyboard uniformed.
