Mellow 80T GT2 Timing Pulley 5mm Bore 6mm Belt | Voron 3D
Mellow 80T GT2 Timing Pulley 5mm Bore 6mm Belt | Voron 3D
Mellow 80-Tooth GT2 Synchronous Pulley for Voron 3D Printers
Upgrade your Voron or any GT2-compatible 3D printer with the Mellow 80T 2GT Synchronous Pulley. Machined from premium aluminium alloy with a high-precision surface finish of Ra0.4μm, this 80-tooth pulley delivers smooth, consistent belt engagement — keeping your motion system accurate and your prints sharp.
Unlike standard pulleys produced with loose tolerances, Mellow manufactures their tooth profiles using specialist tooling designed to pair precisely with Gates-compatible GT2 timing belts. The result is minimal backlash, reduced belt skip, and reliable repeatability print after print.

Frequently Asked Questions
Q: Which 3D printers is this 80T GT2 pulley compatible with?
A: This Mellow 80-tooth GT2 synchronous pulley is compatible with any 3D printer that uses a 2GT/GT2 timing belt system with a 6mm belt width and a 5mm motor or idler shaft bore — including popular Voron builds (2.4, Trident, Switchwire) and other CoreXY or Cartesian designs using GT2 belt drives.
Q: How does this pulley differ from standard, off-the-shelf GT2 pulleys?
A: Mellow uses specialist precision tooling matched to Gates belt tooth profiles, resulting in a Ra0.4μm surface finish and tighter dimensional tolerances. This minimises belt skip and backlash compared to generic pulleys, which can have larger tolerances that cause inconsistent motion and reduced print quality.
Q: Does this pulley come pre-assembled or require installation?
A: No assembly is required. The pulley arrives ready to install directly onto a 5mm shaft. Simply secure it in place and route your 6mm GT2 timing belt — no additional preparation needed.
Q: Is the 5mm bore compatible with NEMA 17 stepper motor shafts?
A: Yes. Standard NEMA 17 stepper motors typically feature a 5mm output shaft, making this 80T Mellow pulley a direct-fit solution for most 3D printer drive systems without any adapters or modifications.
