They hold up, dont strip and dont slip. all I need. I can't imagine a 3d printer putting more stress on them than I do. ### ⭐⭐⭐⭐⭐ On the money *by A***R on 25 February 2024* This was what I was looking for to upgrade to a true dual z axis. Makes my Ender 3 Pro less likely to drift. Great price. ### ⭐ Chinese industrial standards are truly amazing. *by M***S on 24 June 2024* The Chinese can't decide whether they are using the metric system or the inch system? I can't get used to their standards, where the red button is start and not cancel, where 6mm diameter is actually 1/4 inch when the circular saw rotates against the direction of the blades. Do you understand what 6 mm diameter is??! This is when 6.00 +/- 0.05 mm, not 6.3. Why are you sending me this rubbish and why should I then waste my time and money to return it to you? ## Frequently Bought Together - Saiper GT2 Timing Belt Pulley 20 Teeth Bore 8mm(5pcs), Aluminum Synchronous Wheel for 3D Printer - 5M GT2 Timing Belt, Upgrade Non-Slip Version, Width 6mm, Fit for 3D Printer and Most Belt Driven Printers - WINSINN GT2 Pulley 20 Teeth 5mm bore 6mm Width 20T Timing Belt Pulley Wheel Aluminum for 3D Printer (Pack of 5Pcs) --- ## 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.sk/products/358022768-gt2-timing-belt-pulley-20-teeth-bore-8mm-5pcs-aluminum](https://www.desertcart.sk/products/358022768-gt2-timing-belt-pulley-20-teeth-bore-8mm-5pcs-aluminum) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-29*
