Do you think it’d make sense to 3d print parts for any of these fixes?
I bet using a strong-ish material like PETG could be used for the washer at least. Potentially saves a trip to the store.
Maybe it could also work to make a piece that wraps around the clip and allows some straightening from both sides of the clip (with a look that looks more like @arnoldcp’s version in his post Z axis only moving the router some of the time)
Just wanted to put that out there in case anyone has thought about it
