Filament guide arm for Ender-3 S1 Pro

thingiverse

This is a filament guide arm for an Ender-3 S1 Pr. It will guide filament from a filament dryer or other desktop filament stand to the hot head. I did not want to put the dryer directly behind my printer as other designs called for. I wanted more flexibility as to where to sit the filament. My design uses ball bearings so that you can move the pickup arm left or right to whatever direction you want to feed filament from. I used ABS on an Ender-3 S1 Pro, but any filament should be fine. You will need one Arm, one Core, one Cap and four Pulley wheels halves and four pulley/bearing spacers. You will need to print the arm upright and diagonally across the print bed as I want the arm as long as is possible. If anyone wants a shorter arm let me know and I will generate one for you. For hardware you will need one M5X50mm bolt and two M5x25mm bolts and three M5 nuts. The Ender-3 S1 Pro normally comes with some extra hardware and the M5X50mm bolt is the same that is used to attach the uprights. It uses two (625 - 5mm x 16mm x 5mm) and two (685 - 5mm x 11 mm x 5 mm) ball bearings. The 625 bearings are the same that are used in the ball bearing rollers that the Ender-3 S1 Pro uses. It also has a mount for the filament sensor that uses the same hardware that came with the Sensor. This is my first upload, so if I got it wrong please forgive me. If you have any suggestions as to how I can make it better let me know. Enjoy
