Many 3D printers are now moving from T2.5 pitch timing pullys / belts to GT2. This set includes two 20 tooth pulleys and 2 metres of open length belt. This makes it ideal for 1 axis (x or y).

The belt is rubber, fiberglass reinforced, 6mm wide, 2mm pitch. For 3D Printing applications, GT2 2mm belt system works better than T5, T2.5 as it gives better smoothness and accuracy of positioning, resulting in better printing quality. In general, GT2 timing belt systems are especially suited for linear movement and positioning applications so can be used for your DIY pick and place machine as well.

Set includes: 2 x 20 Teeth GT2 Aluminum Pulleys 5mm Bore (fits most stepper motors including NEMA 17), drilled and tapped and supplied with 4 x M3 grub screws + hex key . Also includes a 2m open length of GT2 Fiberglass Reinforced Rubber Open Belt (2mm pitch x 6mm wide).
