UPDATE 2: After several hours of using this, I've managed to optimize my retraction settings to 0.4mm retract speed 30mm/s. If you're experiencing extrusion issues, double-check that your PTFE tube length is accurate. I've just printed a revised version, which is shorter and more efficient. Additionally, I'm working on modifying the original extruder to eliminate the bowden connector and ensure full filament path support. UPDATE: The issue with couplers not aligning has been resolved. For optimal results, use the file named CE3_direct_drive_v1.1.stl. Initially, I printed the original model, but it had a major flaw - part of the design was in contact with one of the wheels on the x-axis and my pc4-m6 coupler was too long. Furthermore, the original hotend fan wouldn't fit properly. To address these issues, I modified the screw holes to slots for adjustment, accommodating the larger coupler and providing more clearance for the wheel. For a sturdy print, I recommend using 10% infill; you may want to increase this value depending on your specific needs. Don't forget that you'll need m3 screws.
