GT2 80T 5mm孔徑皮帶輪，適用于3D打印機(jī)和Voron

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 slide, gear reduction systems, and custom motion :Outer diameter: ~52.6 mmWidth (thickness): ~17.7 mmBore: 5 mmApprox. part volume: ~25,500 mm3 (≈ 30–32 g when printed in PLA/PETG)Features:Standard GT2 tooth profile for smooth belt engagementDesigned for FDM 3D printingCan be used as a driven pulley in belt reduction systemsSuitable for light mechanical motion and prototype assembliesRecommended Print Settings:Material: ABSLayer Height: 0.12–0.2 mmPerimete: 4–6 walls for tooth strengthInfill: 50–100% (higher is better for load-carrying)Print Orientation: Flat on bedOptional: Add a press-fit shaft key, iert, or set screw depending on your motor shaft styleApplicatio:3D printe, core-XY systems, plotte, robotic arms, reduction drives, and educational mechanical models.**2) GT2-80T Timing Pulley (5mm Bore) – Companion Veion for GT2-20T-6mm PulleyDescription:This veion 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 e:Use this 80T as the large pulley and pair it with a 20T driving pulley to achieve a 4:1 reduction ratio. Perfect for applicatio requiring increased torque, finer motion resolution, or smooth camera :Outer diameter: ~52.6 mmWidth: ~17.8 mmBore: 5 mmApprox. part volume: ~23,500 mm3 (≈ 27–29 g in PLA/PETG)Features:Matched geometry for GT2-20T-6mm pulley pairingWorks with GT2 6mm beltsDesigned for smooth compound pulley alignmentSuitable for precision reduction drivesRecommended Print Settings:Material: ABS recommended for belt grip stabilityLayer Height: 0.12–0.2 mmWalls: 5+ perimeteInfill: 60–100%Print Orientation: Flat on build plateSuggested: Light post-process sanding on bore for precise shaft fitUse Cases:Camera slideMotor torque multiplicationCNC Z-axis driveRobotics with fine angle resolutionDIY planetary or belt reduction gearboxes
