This one came out pretty well and is the most complete 360 degree gnome scan yet. It was also the first scan using my new printed turntable and spinscan software from http://www.thingiverse.com/thing:9972

Spinscan isn't calculating the Z axis correctly, so if you download the point cloud you'll see it was stretched. I had to shrink the Z axis in blender. Other then that and 2 steps in meshlab, it required no cleanup or merging of multiple point clouds, spinscan got a complete scan of all sides in one go.

This extension connects Thingiverse with Makeprintable, a cloud-based mesh repair service that analyzes, validates and repairs most common mesh errors that can occur when preparing a 3D design file...

this is absolutely awesome.

Great !

What steps you did in Meshlab ?

Basically 2 filters in meshlab: Point Sets -
gt; Compute normals, set neighbors to 100. Then Point Sets -
gt; Surface Reconstruction: Poisson, set octree depth to around 8 or 9. Then export to stl.

Then load the stl into blender and scale the Z axis down until I fix the math in the spinscan software and/or do a boolean subtract with a square to give it a flat bottom to make it easier to print.

Ys a short readme would be nice :)
