CR6SE dual gear extruder adapter

Replacing the standard Ender CR6 SE extruder with one of the many dual gear clones requires to modify the path from the filament sensor, eventually requiring to leave the filament sensor hanging, because the dual gear extruder are thicker and the filament position is shifted up with respect the CR6 SE standard extruder.

This model provides an 8 mm spacer to be installed below the filament sensor, re-aligning the filament sensor with the point where the filament enters the extruder. The spacer has the same shape of the original filament sensor and can be using regular M2 screws, longer than the original ones, up 30 mm.

Additionally, it is possible to add a roller using the uses a 608 bearing to smooth the path from the filament spool to the sensor.

Because the roller is a nice addition to reduce the friction between the filament the sensor, but nothing more, a simple model, without the brackets required to fix the roller is available.

Print setup and installation

Place the STEP or STL file in the slicer, no supports are required. A 0.2 mm high is suggested, to improve the shape precision.  The area becomes quite warm during the printing, for this reason I have personally preferred PETG.

Place the spacer below the filament sensor and use 2 M3x30 screws to attach the elements to the frame.

If the roller is printed, press the bearing into the circular guide, insert the guide into the location and use a M8 screw and bolt to secure it.

How to modify it

If the high of the entry point of the filament is not correct, because your extruder is slightly  higher or lower, use the STEP file to modify the model with the roller bracket or drop a comment, rescaling this specific model with the slicer may have negative effect on the shape of the bolt installation. The simpler spacer can instead be easily rescaled.
