Hi, yes this one is not printable and i render it just because it was nice to see. A lot of my meshes are not printable due to the small parts not connected and also because they are really to big (between 300 Mb and 1,5 Gb) i'm working to obtain smalest meshes with good quality. Due to the memory limitation of Netfabb i must rework all my meshes at 400x400x400 voxels because now i work at 1000x1000x1000 voxels to obtain a better accuracy. I really like your 3D meshes, you really made good works. Thank for your comment
I also work between 300x300x300 (with and resampling factor=1 in Fiji) sometimes up to 800x800x800 (with resampling factor =2) then I decimate in Meshlab to get less than 1 million faces for Shapeways. The resulting STL file size after repair in Netfabb is typically 50Mb big. Thanks!
