Great part but you need to nail the print quality here or the plugs definitely won't fit. I redesigned them to compensate for a very tiny 2% overfill on my machine and got them working.
Only problem is I have a Romax + repeteir and I cannot for the life of me get the printer to understand it has FSRs attached... how is this procedure done? There is ZERO documentation online.
Also an M4x10 right through the plug will screw in nicely to the melamine snowflake.
