Gear and Mount for Slip Ring

thingiverse

A gear designed to work seamlessly with this slip ring, along with a mount and gear tailored specifically for use with a 28BYJ-48 Stepper Motor such as this one, is required. The slipring gear boasts a 1mm pitch, 54-tooth configuration. The grommets and washers facilitate the use of M3 screws without nuts. The gear for the stepper motor features a 1mm pitch, 15-tooth design. Depending on print accuracy, you may need to secure it in place with a M3 screw. Mine fit snugly over the stepper motor's output shaft with a small amount of force. The bracket requires two M3 screws to mount securely to the stepper motor. The holes for the slip ring don't align perfectly, but you can easily persuade the grommets to pass through with minimal effort. I failed to anticipate the difficulty of holding the grommets still while inserting the screw, so they'll have to be gripped firmly with a pair of pliers or something similar until I update them.
