This is a switch machine that works with only weights. I call it Gravity-Switcher since it is gravity working on the weights that make it work. It is set up very similar to the servo switch machine that you can find with my other prints here.

If interested one really needs to review this item on my website here....

Also there you will find the other pieces that will help make it work, Push-Pull and Lever controls for the edge of the layout and pulleys and line adjusters to run the control line from the Gravity-Switcher to the controls at the edge of the layout.

Prints were printed with an Ender 3 Pro using Cura set on 'Standard Quality' in the 'Profile' setting for the larger pieces and on 'Super Quality' for smaller pieces like the individual windows. The printer has a stock .4 nozzle with 'supports' selected.
