Gear range M1 with chain

Having the full tooth range from 10 to 60 means I can fine-tune the speed and torque on my builds, and the metal chain links are solid and don't slip under load. It's a great little parts kit for expanding the possibilities of any construction set.

The 10-to-60-tooth range means I finally had the right ratio for a slow, steady lift instead of guessing. The 1 m chain runs smooth around the sprockets with barely any slip. My builds actually move now instead of just sitting there.

I grabbed this to add moving parts to my son's construction set and the 12 gears from 10 up to 60 teeth gave us way more combo options than I expected. The 1 m chain links up nicely and actually stays on the sprockets while it runs.
