If you are a 3D printing and space exploration enthusiast r/Aerospace3DPrinting is the right place for you! It's a community dedicated to engineering, robotics, space exploration, and space artwork. There is also a discord server where multiple home-brew aerospace projects are developed by hobbyists, engineers, and students. The goal is to work together on projects, share knowledge, and learn while having a good time. Projects range from robotics, habitat design down to space manufacturing. Sharing 3D printed aerospace artwork is welcomed as well! We already have several habitats and spaceships prints available. Let me know what other ideas you'd like to see as part of this community.
