Pull Start Spinning Top Launcher

Pull Start Spinning Top Launcher

This is a mechanically powered spinning top with a rack and gear launcher.
The top is accelerated by pulling the rack, which spins the gear inside the launcher and gives the top a fast and smooth start.
The model is easy to print and works as a fun mechanical toy. Just insert the spinning top, pull the rack, and watch it spin.

Assembly

Notes
Print all parts separately.
PLA works well for this model.

Two parts need to be glued together: Spike Pin and Disc.
Use a small amount of super glue and make sure the spike is aligned straight with the disc before the glue sets.

It is recommended to lubricate the gear teeth with silicone oil or candle wax for smoother operation.
