1 Total Rear Holder
1 Adapter spacer 6x8mm
2 Filter Filament
2 Conical Pulley
The flat washer is only necessary if the M6 bolt has a head that tends to fit the bearing and it is necessary to distance it.
The spacer adapter must be positioned between the pulley and the Total rear holder.
To complete the project you need:
The run-out sensor holes are slightly wider to allow perfect centering with the upper hole and also with the filament tube.
The support attaches to the printer via the snap clips in the rectangular aperture, making it more stable with two small strips of double-sided tape. The magnets are removable if the orientation is wrong, once you find the correct housing we recommend putting a small drop of Loctite Attak (cyanoacrylate glue). The two parts of the pulley fit together using the ball bearing, but even here two drops of Loctite Attak block everything.
