Gravitrax tunnel spacer

A tunnel spacer to be used together with my Gravitrax base tile. It adds 10mm to the height of the base plate and can be stacked with all types of Gravitrax building elements above.

No support is required if printed upside down as oriented in the files.

I also include two variants, one that fits the alex80it baseplate and one that fits the JDO solutions (Oostmeijer) baseplate.
