I’ve never used a 3d printer before but want to get one. I have a bit experience in blender but not too much. My question is: How do you model for a 3d print? For example, if I want to print a hollow cylinder, I go into blender, create cylinder and delete the side faces. If I print this, the walls will be pretty thin. Do I have to make them bigger manually? and if I do so (extrude and scale) does my slicer (cura) automatically fill in the solid part?

    If you’re new to 3d printing, I would avoid Blender. It’s too easy to create non-manifold and non-watertight objects with it.

    In your example, the walls aren’t just thin, they have no thickness whatsoever and would not even appear in your slicer.

    I would recommend trying Fusion 360 if you’re not on Linux, openSCAD if you have a basic understanding of coding, or even TinkerCAD (web based) if you’re not making anything too complex. Those are made to create physical objects.

      Onshape is also good, the free version has all the functionality you could want unless having private models is important to you

      Fusion360 can run on linux using WINE, HERE is a GitHub repo showing how to set it up.

      Or the web version works on linux too ofc

      That being said I use and recommend onshape if you aren’t planning on doing this for a company professionally that already uses F360

        Good to know! I just saw a post somewhere around here recently by someone who had troubles on Linux, which is what I based this off of (a little hastily).

          Ya I don’t doubt people have troubles with it since you need winetricks and such. Hopefully they see that github page eventually and get it working.

        NIce! I spent weeks trying to get Fusion 360 to run in wine back in 2020. Eventually I gave up and learned Free CAD/Open scad/blender like all the other penguins.
