DIY Linear Guide with Leadscrew Mechanism | Proof of Concept

In this video, I continue exploring different ways to convert rotational motion into linear motion. After testing a crank-slider mechanism and a belt-driven linear guide, this time I’m trying a leadscrew-driven linear guide — a simple proof of concept using a 3D-printed carriage, an M5 bolt and nut, and a NEMA17 stepper motor. Leadscrews offer several advantages over belt or crank systems — they’re precise, self-locking, and require very little maintenance. In this build, I show how the mechanism works, how I embedded the nut into the carriage with a soldering iron, and what I’d improve in the next iteration. 🧩 Parts used: NEMA17 stepper motor M5 bolt (temporary leadscrew) M5 nut (lead nut) 3D-printed carriage (PLA) Linear guide rods Shaft coupling 🔧 Next improvements: Support the leadscrew on both ends with bearings Fix the lead nut more securely between two printed parts 💬 Have ideas or suggestions?
