MK8 3D Printer Conversion, Laser/Spindle Engraver

Conversion parts and interchangeable mounting bracket for installing a MK8 all-in-one, direct drive extruder/hotend on a laser/spindle CNC engraver. Switch between 3D printing, spindle motor engraving, and laser engraving. Fits engravers that accept a 33mm square laser body and is height-adjustable within the engraver's clamp for bed leveling.

The NEMA 17 motor clamp of this adapter requires four M3x20mmL screws and nuts. The filament cooling version of the clamp also requires a 40mm blower and four M2x5mmL screws.
