Gearbox works really well plenty of torque for my project. ### ⭐⭐⭐⭐ Good, but bare wires which is a minor annoyance. *by J***S on 30 April 2026* I bought this with a set of non gearbox Nema 17 motors from the same company. It kinda annoys me that the shaft is a different diameter. The mounting is completely different. There wasn't a connector and is just bare wires. None of that is the end of the world, but it's an annoyance if you want to quickly prototype. ## Frequently Bought Together - STEPPERONLINE 5:1 Planetary Gearbox Nema 17 Stepper Motor 0.4A for DIY CNC Robot 3D Printer - STEPPERONLINE Nema 17 Stepper Motor 26Ncm(36.8oz.in) 12V 0.4A 3D Printer CNC - STEPPERONLINE Nema 17 Bipolar Stepper 12V 0.4A 56.7oz.in/40Ncm Hybrid Stepper Motor 3D Printer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/254504821-5-1-planetary-gearbox-nema-17-stepper-motor-0-4a](https://www.desertcart.tn/products/254504821-5-1-planetary-gearbox-nema-17-stepper-motor-0-4a) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
