I design parts for 3D printing, and the annoying part has always been that proper CAD needs a laptop and a mouse. The phone apps I tried were either viewers or too simple to make real parts. So I've been building a CAD app that works with a finger or a stylus. The video shows an M12 bolt with real threads, modeled entirely on my phone. How it works for printing: - Sketch with exact dimensions (snapping or typed values) - Extrude, fillet, chamfer, shell and pattern for the actual shape - The solids are watertight, so the STL should go into a slicer without a repair step - STEP export too, if you want to continue in another CAD tool Besides the bolt I've modeled a kettle and a crankshaft, and a whole villa, all on the phone. It's still early, so I'm looking for honest feedback from people who print: 1. Would you design parts on a phone, or is a screen that size a dealbreaker? 2. What's the first missing tool that would stop you from using it for a real part?   submitted by   /u/Haunting-Investment6 [link]   [comments]
