"Holo clock" parts for 28BYJ-48 geared stepper motor
thingiverse
The "holo clock" design by ekaggrat is at http://www.thingiverse.com/thing:570797 I built a motor gear that fits the axle of the 28BYJ-48 5V stepper motor perfectly. The M3 grub screw was optional for my case, as it fit like a glove. I also customized the motor mount to accommodate the motor bearing collar. Currently, this is an evolving design, and I haven't completed my final build yet. The 28BYJ-48 stepper requires modified electronics too, so it's not compatible with ekaggrat's solution.
