KARAKURI：如何製作會動的機械紙模型

The cam and gear sections finally clicked for me after building the sample models—the instructions walk you through each mechanism without assuming you're an engineer. My first crankshaft bird wobbled a bit, but it taught me more than any static craft book could.

The step-by-step photos for the cam mechanism finally made it click for me—I'd struggled with similar builds before, but the way each gear and lever is broken down feels genuinely foolproof. I've already finished the first two automata and they move with a satisfying smoothness I didn't expect from

The crank and lever projects are the first ones I tried and they actually move smoothly once the paper is folded right. I've spent three evenings on the cam mechanism alone and it's oddly satisfying to watch it click through each rotation.
