Replacement Machined Hot End Mounting Block for the MM3. This is the old style block that used set screws rather than the new clamping style. It does support dual extruders, but the clamping style offers much easier hot end leveling, so we recommend dual-extruder users upgrade to that style rather than replacing this part.
Includes the block and all required mounting hardware. Does not include the hot ends, X Carriage or any other extruder parts.
