Bandvagn 206 track model

This is very much a work in progress, the scale is not defined, fit not even guaranteed, going by trial and error.

The existing CAD programs didn't work anymore and can not be edited anymore. Now drawing in Openscad.

Only just completed the suspension carrier with suspension arms and wheels. It looks very similar to the BV206 track carrier but will likely end up as a tracked platform.
