I'm looking to 3D print an iwata jlmc horn for a DIY speaker project. I manage to import a cloud point from a JMLC excel file into mesh lab but the points are (I think) not sufficient to create a proper surface for the object. I would like to then export into an stl file for a print.

I know that they are solutions with algorithms to get to the point where the cloud would have the desired form but I don't have sufficient knowledge to get there. Another solution would be to make splines? and push the file into fusion.

Anyone has an idea? I'm attaching the screenshot of meshlab screenshot of meshlab

I've tried the following:

• Import the point cloud
• Calculate the normals (perpendiculars, if you like) based on the points (Filters – point sets – compute normal)
• Using the normals and points, create a 3D surface (Filters – Remeshing – Surface Reconstruction, Ball Pivoting)
• Recreate the face normal based on this new surface (Filters – Normals – Recompute Face Normals)

It's show something but only on part of the horn which is useless. Poisson technique is also strange looking
