Funsor makes all aluminum parts for the conversion. I will use these as replacement on the ender and a Voron 2.4 R2 printer. Many uses beyond just printers too. ### ⭐⭐⭐⭐⭐ Accurate pulleys. *by A***R on April 25, 2026* Accurate specs. Well made. They seem as good or better than the stock and the price was good. ### ⭐⭐⭐⭐⭐ Great quality pulleys—perfect for my CNC build *by D***R on July 18, 2025* I used these WINSINN GT2 idler pulleys as part of a custom CNC printer project, and they worked out better than expected. The aluminum feels solid and well-machined, and the 20-tooth profile lined up perfectly with my 6mm timing belts. Installation was quick—everything fit snugly on the 5mm shaft, and the movement stayed smooth without any wobble or noise. I’d definitely use them again on future builds. If you're working on a 3D printer or CNC system, this will do the trick. Reliable, clean finish, and no headaches. --- ## 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.com.cy/products/65860428-winsinn-gt2-idler-pulley-20-teeth-5mm-bore-for-6mm](https://www.desertcart.com.cy/products/65860428-winsinn-gt2-idler-pulley-20-teeth-5mm-bore-for-6mm) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-04*
