GRAVITRAX compatible spiral

Another GRAVITRAX compatible tile, but not so often available : the spiral

I have improved the concept by designinning an intermediate entry so you can enter the spiral at any level you want
Each 1/3 of a turn is 5 mm high, meaning you can adap^t the entry to the level you want

And you have several length of central pilar in order to make it as high as you want

If you need more than 110 mm, please ask I will upload new version

Depending on the precision of your printer you will have to adjust the iner circle and the shape of the tile to put in place the exit turn : it might be a bit tricky

Enjoy your game
