3D Pelton buckets

Hello everyone,

we are a group of Mechanical Enginereeing student. We have to create the 3D model from a STL file using the reverse enginereeing process.

Here are three views of the file:

Laboriously we managed to get to this point but we do not know how to rebuild the central layer and the excavation at the top.

Here are three views of what we have done:

Any suggestion?

Thank you all

Zip and attach your *.sldprt file here.

Attach the *.stl too, if it isn't embedded in your slprt file.
