During a marble run build on a weekend, as many of you know, you are lacking of parts and the shops are already closed or don't have them in stock.
So did i with some switch tiles. The easiest way is to search for a 3D printable part, but nothing found.
Now it was time to reactivate my Fusion skills and i have build one my own from scratch based on the messurements from a 2-to-1 tile. 

It works with the original switches from Gravitrax and the switches from below.

The only parts i have found were the one-turn left and right switches from the following project from Bingobricks:

I have added them as a second print profile and additionally added a merged part so that there are the

following switch parts available to work with my design:

• One turn left.
• One turn right.
• Left and right turn.

The axis on the bottom are very snug and press fit. (No glue needed)

Enjoy your next marble track build.
