Show HN: Browser CAD for stock-tube structures with generated 3D-printed joints(Submitting as TrussLab's UI designer - my husband Jan built the editor and wrote the text below; he's answering questions in the thread as janherich.)The linked demo opens TrussLab with a deliberately simple triangle frame and walks through its construction in real time, with narration. You can sit back and watch, orbit around the model without interrupting autoplay, pause or resume the build, or take over at any point and edit it yourself.TrussLab grew out of my earlier work on SpaceDelta3D large-format delta printers and ultralight SpaceDrone quadcopter frames. At that time, the tooling was just a collection of Clojure scripts that I interacted with from a REPL to generate OpenSCAD models. The underlying idea is simple: use straight-cut tubes or rods made from metal, composites, or even wood for the long members carrying tension and compression, and 3D-print only the geometrically complex joints. Keeping the printed parts small reduces print time, failure risk, warping, and the cost
