Slightly off topic, but...<p>I have a 3D printer and am proficient in designing with Fusion 360 and similar software. I've also experimented with newer approaches like Shapr3D on the iPad and a few others. However, I often find myself too unmotivated to design quick, "necessary" items with the existing tools. They are excellent, but can create a significant gap between my mental image of the physical object and the modeled one. I'm optimistic that emerging innovations in this area will bring more natural and intuitive design approaches to the DIY community. It's exciting to imagine the development of tools with simple flow, non-destructive operations, and accurate sizing, among other features.<p>One challenge, however, is affordability; it's often difficult to justify paying premium recurring prices to design occasional and unconventional items, such as a revolutionary toilet paper holder.<p>(I'm always torn between code-reliant approaches like OpenSCAD and intriguing but not fully mature options like CadQuery, which are somewhat unintuitive but easy to follow, parameterize, and push on git, and the opposite graphical options like the old SketchUp, TinkerCAD, and the like).<p>Something is missing. Something that makes us feel like we are modeling with our hands, paper, and wood, but without having to constantly glue our fingers together.
