Print Profile(2)
Description
Cycloid Spinner - a mesmerizing 3D-printed fidget toy built around a cycloidal gear mechanism. Spin the central gear and watch the inner discs orbit in hypnotic, rolling-circle motion. Fully printable, no supports needed, press-fit assembly - no glue, no screws.
Assembly Instructions:
Insert the central shaft into the center hole of one of the hypocycloid discs. | |
 |  |
Place the second hypocycloid disc onto the axle and check the markers on the side to confirm correct alignment. | |
 |  |
Slide the 4-arm plate down over the axle so its pins drop into the disc holes. | |
 |  |
Drop the assembled disc stack into the ring housing. | |
 |  |
Install the top sun knob onto the shaft from above and the knob on the bottom, then press both until they click into place. | |
