I am a CAD designer who has been designing 3D objects for quite some time now. I specialize in the software Autodesk Fusion360. I also dabble in TinkerCad, which is much simpler and easy to use. Most of my designs here are posted on Reddit much earlier than they arrive for here and are downloadable. If you would like to see some of my designs before they arrive here, check me out! I usually post on r/3Dprinting as u/jacemakes
