Here’s my take on a slow feeder for the Timemore Sculptor 064.
It uses an on/off toggle switch, a PWM controller for variable speed control, a USB-C charging module on the back, a 14500 Li-ion 800 mAh battery, and a mini N20 gear motor. Everything is housed in a custom 3D-printed enclosure. Takes about 5 Hrs to print

Print the Feeder Disk in PETG. 

Assembly Instructions

Motor Installation:

To insert the motor, slide it in about halfway, then press it firmly into the side clips.
It’s designed to be a tight, secure fit, so push until it fully snaps into place.

Battery Installation:

Push the 14500 Li-ion cell into the printed battery clips.
It should click in snugly and sit firmly without wobble.

USB-C Charging Module:

The USB-C charger module installs the same way—align it with the printed slot, push it in, and it will snap into the retaining clips.

Feeder Disk:

Push the bearing into place
