The first prototype model is here
The struts are a little too thick for the holes, so I'll widen the holes a little in the next version.
Also, there were a few struts missing, so I think I'll add a few extra on the model (it's understandable that not all of them make it through production)
As for this prototype, I would like to try and assemble it, despite its flaws, so I was wondering what kind of glue works best with the full colour sandstone. Also, I think cutting open the holes more or thinning the struts might be quite difficult, so would just filling the holes with glue and sticking the struts on top work?
