About this model

This is a modification of the stock mk3 filament sensor cover that adds M6x5.75mm threads. These threads allow the attachment of a PC4M6 connector to connect a Bowden tube. I left the same space within it for the short ptfe tube that inserts into the stock cover. I am using this with ctilley79's modified Z tops that include M10 threads for a pass through PC4M10 -> - I recommend it!! ....Print this in black as Prusa has stated there are some issues with the sensor with other colors.
