This is a remix of the Artis3D KKm extruder with simplified BOM, adjusted tolerances, and using bigger (4.6mm-5mm OD) heat inserts.
It is also compatible with the LDO 36STH20-1004AHG motor (10-tooth version), that offers increased output torque due to 10-tooth gear, has better wires less prone to breaking, and makes a future upgrade to Orbiter/Cyclops cheaper.
Do not forget to separate parts in the STEP file before printing! The file contains 4 parts total.
You will need:
- All the gears and bearings from the stock extruder
- 1x ECAS04 fitting
- 2x M3 washers (1mm thick, only for stock K1 motor)
- 4x MR84ZZ bearings
- 6mm long piece of M2 screw (without head)
- 2x 4x15mm pins
- 1x tension spring
- 1x M3x10 or longer SHCS screw
- 3x M3x18 SHCS screws
- 1x M3x20 FHCS screw
- 5x M3 heat inserts (4.6mm-5mm outer diameter, up to 5mm length)
Optional components:
- LDO 36STH20-1004AHG (only 10-tooth version, 8-tooth will not fit!). It is a better option to replace the stock motor if it's broken. Replacing the stock motor with LDO if it works fine makes no sense.
- DLC hardened gears by Trianglelab to print composite filaments
If you use the LDO motor, set the rotation_distance to 5.75 and the current to 0.7.
