Hi. first of all your work is great and extremely helpful.

I noticed that you guys model originals in rhino; so do I. I have a question. Do you guys mesh the NURBS surface then export as stl or export to stl directly from the original mesh surface?

The reason i ask is because I'm not getting consistent results on my prints, especially for smaller prints like rings, large objects seem to work all the time.

Thanks

Thanks for the comment and kind words :)

Rhino 3D is somewhat of a work-horse for us here. Very good design software.

The NURBS model is made into an STL mesh inside Rhino 3D via the command "Mesh". This lets you adjust the mesh resolution to what you prefer.

Then the actual mesh object is exported to an STL via File > Export selected.

A quick wash through netfabb Studio lets us be sure that the mesh is correct and does not have any defects.

It is difficult to know exactly what the defect in your smaller models is. I think though that a higher-resolution mesh should solve the problem. :)

This the same work flow I go through. I will try and meshing at a higher res.

Thanks, and cant wait to print the filament dust filter.
