Thanks for the lesson. Beware a smiling geek. He has an idea he want to try.They left for the long weekend already...
After digging through the net for hours, I came to a solution... I knew I needed a feew beers to clear my head. It looked like the vertices were all there, only the facets were missing at some areas. After importing it to Meshlab, I started by getting rid of the single large triangle on Q2.

Next, I exported the point cloud only , then re-import it again

Next I used a function to recalculate the normals for each vertex, need to be able to re-mesh the data. The "hairs" are the normals

Meshlab has a convenient function to recreate the mesh called "Screened Poisson Surface Reconstruction" which does the trick, although it takes a few minutes to compute.

After inverting the normals:

Turned into a solid model with Meshmixer... now's off the the printer and I am left to enjoy my holiday
