This is how you turn your Gravitrax marble run into a “perpetuum mobile”.
This XXL lift (3D printing) has 3 entrances at the bottom and 3 exits at the top (22, 18 and 12 cm). This means you can build 3 different routes at the same time.
You can watch the balls rise through the open walkways.
The lift is printed in 1 part and is therefore very stable.
With my lifts, the ball runs reliably into the entrance and does not have to be pushed by a subsequent ball.

In addition to the lift, you can also purchase optional ball entrances. These can be attached to the lift at any height and provide an additional entrance for the balls.

Here is the presentation of my lifts from “Coogelbahn” on YouTube:

There you can also see my height stones in use...

Here is another video that shows the function of the optional additional ball input:

The lift requires 2 AA batteries (not included).

The more balls, the more fun.
That's why there are 5 silver steel balls included.

There are also optional balconies especially for my lift. These can be attached to the lift in any position. This can save you a lot of elevation stones.

Return possible within 14 days!

I also offer lifts at other heights.
Also note my Gravitrax compatible height stones. Ideal as an addition to the lift.
