so far it works great but i suggest getting a really thick walled piece of tube, i wore through mine pretty quick and was hitting the screw holding it!
One issue. It appears that if you use a screw to hold the cutting blade into place, it doesn't allow for travel into the holder. This wall needs to be raised about 3mm for space for a button head screw.
Love it! This is the filament cutter my merc has been waiting for.
@PhotonLight_500331 Glad to see that the left side works okay!
