You're right. 3d printing is a new technology and so it need an appropriate design mode for the manifacturing of the objects. Just for that is important the know how of the technology and related materials. But are also important the tools (software&hardware) and the help of the community, that I want to thank.

Ok. GregValiant, I'm a newbie for 3d printing but I'm very old in cad design. Your suggestions have been very useful. I've thought that adding a ''solid mesh'' but I didn'n know how to tell to Cura the appropriate settings. Thanks a lot. Have a good day.

It's possible to fill a close profile with a hatched solid filling without the top and/or the bottom layer with Cura? In other words, how to make a grille with height inboud this profile? Cover-A.stl
