GT2 80T 5mm Bore Pulley For 3D Printers & Voron · 模型 216123
1) GT2-80T Timing Pulley (5mm Bore) Note:- If you make and use this pulley kindly do not forget to comment. Description: This is an 80-tooth GT2 timing pulley designed for 5mm motor shafts (typical NEMA17/mini DC motor size). Useful for belt-driven CNC, robotics, camera sliders, gear reduction systems, and custom motion assemblies. Dimensions: Outer diameter: ~52.6 mm Width (thickness): ~17.7 mm Bore: 5 mm Approx. part volume: ~25,500 mm³ (≈ 30–32 g when printed in PLA/PETG) Features: Standard GT2 tooth profile for smooth belt engagement Designed for FDM 3D printing Can be used as a driven pulley in belt reduction systems Suitable for light mechanical motion and prototype assemblies Recommended Print Settings: Material: ABS Layer Height: 0.12–0.2 mm Perimeters: 4–6 walls for tooth strength Infill: 50–100% (higher is better for load-carrying) Print Orientation: Flat on bed Optional: Add a press-fit shaft key, insert, or set screw depending on your motor shaft style Applications: 3D printers, core-XY systems, plotters, robotic arms, reduction drives, and educational mechanical models. **2) GT2-80T Timing Pulley (5mm Bore) – Companion Version for GT2-20T-6mm Pulley Description: This version of the GT2-80T pulley is modified to be used together with a GT2-20T (6mm belt) pulley in a compound / gear-reduction arrangement. Ideal for belt-based speed reduction while keeping systems compact. Purpose: Use this 80T as the large pulley and pair it with a 20T driving pulley to achieve a 4:1 reduction ratio. Perfect for applications requiring increased torque, finer motion resolution, or smooth camera movement. Dimensions: Outer diameter: ~52.6 mm Width: ~17.8 mm Bore: 5 mm Approx. part volume: ~23,500 mm³ (≈ 27–29 g in PLA/PETG) Features: Matched geometry for GT2-20T-6mm pulley pairing Works with GT2 6mm belts Designed for smooth compound pulley alignment Suitable for precision reduction drives Recommended Print Settings: Material: ABS recommended for belt grip stability Layer Height: 0.12–0.2 mm Walls: 5+ perimeters Infill: 60–100% Print Orientation: Flat on build plate Suggested: Light post-process sanding on bore for precise shaft fit Use Cases: Camera sliders Motor torque multiplication CNC Z-axis drive Robotics with fine angle resolution DIY planetary or belt reduction gearboxes
