Maximize your printer’s resolution and torque. This 16-tooth GT2 pulley is the preferred choice for builders looking to fine-tune their motion system. Precision-machined from high-grade aluminum, it provides a smaller pitch diameter than standard 20T pulleys, offering superior mechanical advantage for X, Y, and Extruder drives
$5.29
16T GT2 Timing Pulley aluminum with 5mm bore. Used with GT2 Synchronous Timing Belts where mechanical transmission is required.
Specifically sold here for the Voron 2.4 3D Printer Build. 4 are required. For reference the Voron 2,4 build manual can be downloaded here. Used on the Z Carriage Motor Drive. 4 Pieces Required

Installation Guidelines
Steps-per-mm Update: Remember to update your printer firmware (Klipper/Marlin) settings when switching from 20T to 16T pulleys to maintain dimensional accuracy.
Shaft Mounting: Align one of the dual M3 set screws with the flat portion of your motor shaft. We recommend a drop of blue thread locker for high-acceleration “SpeedBenchy” builds.
Belt Path: Ensure the belt is centered on the pulley to avoid rubbing against the flanges, which can cause premature belt wear.
Maintenance
Debris Check: Occasionally inspect the tooth grooves for belt dust or debris buildup to ensure perfect engagement.
Cleaning: Use a dry, soft brush or compressed air. No lubrication is required for the pulley surface.
