This extruder is a remix of the Bear Extruder for the Copperhead hot end made by Slice Engineering with the addition of the bondtech idler lever arm. I made models for both the groove mount and screw mount variants and will fit the MK3S and MK2.5S. If you are looking to buy a Copperhead hot end, I would recommend getting the screw mount variant and using the T-Attachment component. This locks the hot end in place to prevent it from rotating. Assembly is the same as the bear extruder, except you will be using a hex nut in place of one of the square nuts.
