Klover Extruder V1.3A direct drive extruder conversion for the Creality CR-10 series of 3D-printers using only the standard extruder parts.You will need an assortment of M3 screws from 6-35mm in length, a couple of M3 nuts, and an extension cable for the extruder stepper motor.V1.3 fixes and improvements: • Improved part cooling. • The filament gear tension screw is now accessible from beneath the extruder without any disassembly - as shown in one of the images. • Some other small changes have been made, so the extruder is now easier to assemble and disassemble than ever.V1.2 fixes and improvements: • Improved printability - both less support and less time to print. • M3 nuts added at the structurally important fastening points instead of just threads in the plastic. • The rigidity of the PTFE tube internally in the hotend has been improved by adding two support plugs in the thread where the quick disconnect fittings for the PTFE tube were previously.V1.1 fixes and improvements: • Improved rigidity of the stepper bracket. • Improved rigidity of the energy chain mounting point. • The part cooling bracket sagged because of prolonged heat exposure when not running the part cooling fan. The part cooling bracket has been redesigned to resolve the issue. • Small irregularities in the CAD model have been fixed.As far as I know, the CR-10 series all share the same Z-assembly and hotend carriage, so this should work on all models of the CR-10 series. This extruder has only been tested on a CR-10 max, so I will not guarantee the fitment on other models.Credit to Nguyen Nhu Tuan for the model of the frame I designed this around.
