Hi!
I have been developing a pieze for 3D printing, it is composed of 2 parts:
One is the base and is supossed to be printed in PLA or ABS and the other one is the pusher and its suposed to be printed in flex filament.
But the .stl file of the second part isn’t working properly, it is not beign read by the Cura.
Is there something worng in the code?

Please post the resulting STL file.
My guess is it is not closed and watertight.
Moved to Grasshopper category
Results from the “Check” command:
This is a bad mesh.
Here is what is wrong with this mesh:
Mesh has 248 non manifold edges.
Skipping face direction check because of positive non manifold edge count.
Mesh has 4348327 pairs of faces that intersect each other. This can cause problems if you’re doing mesh boolean operations with it.
General information about this mesh:
Mesh does not have any degenerate faces.
Mesh does not have any ngons.
Mesh does not have any extremely short edges.
Mesh does not have any naked edges.
Mesh does not have any duplicate faces.
Mesh does not have any disjoint pieces.
Mesh does not have any unused vertices.

Object name: Rhinoceros Binary STL ( Jan 29 2019 )
Layer name: Layer 01
Render Material:
source = from layer
index = -1
Geometry:
Valid mesh.
Closed double precision polygon mesh: 25919 vertices, 41472 faces with normals
Bounding box: (-26,-26,9) to (26,26,17)
So, how could I fix the mesh, I followe the same steps than I used for other parts and they worked.
John is correct - your curved Brep file is not correct. You can easily tell this by looking at the bottom of it with 100% opacity:
Any time you see something like that you know you’ve got a big problem. Geometry like that will never produce a printable STL file because your slicing software will not know how to interpret the resulting STL file. Also, the final output for that geometry says it is an Untrimmed surface. That’s telling you the same thing - an STL file made from this geometry will not slice OK.
I attached a different (and simpler) way for you to make this geometry. The key difference is to use closed Breps whenever you can. A closed Brep will produce a sliceable STL file almost every time.

Thanks!
