Chiron Filament Pulley

thingiverse

Filament Pulley for Anycubic Chiron I recently acquired an Anycubic Chiron, and immediately noticed the awkward angle of the filament relative to the filament sensor when the Z-axis elevates. To rectify this issue, I created a pulley that alleviates some tension and prevents the filament from snapping. Two distinct rollers were designed: one simply printed and mounted, and another incorporating a 693ZZ ball bearing (3x8x4mm). Although I prefer the bearing-version, the solid roller functions adequately if not overtightened. A small roof was added to the top of the pulley to prevent the filament from dislodging when pushed back. So far, this solution has worked efficiently for me; however, if you discover any areas for improvement, please do not hesitate to share your suggestions. To assemble the pulley, three M3x20mm screws and three corresponding nuts are required. Depending on your selection of roller, an additional 693ZZ ball bearing (3x8x4mm) may also be necessary. This pulley was printed in PLA with a layer height of 0.1mm and without any support material.
