✔️ 6.35mm bore (0.25"), 24 teeth, 3mm HTD pitch, 15mm wide belt groove, single unit

This aluminum timing pulley drives the drive belt in belt-driven 3D printers and stepper-motor assemblies. It fits 6.35mm shafts and 15mm wide HTD3M belts, a common choice for RepRap, Kossel Delta, and similar printers.

✅ 6.35mm bore
✅ 24 teeth
✅ 3mm HTD pitch (HTD3M)
✅ 15mm belt groove width
✅ 2 set screws to secure to shaft

💡 What is a timing pulley used for in a belt-driven motion system for 3D printers?

In short, it keeps belt timing tight and torque transfer reliable.

- Synchronizes motor rotation with the belt drive for precise axis movement - Reduces belt slip and backlash in compact printer layouts - Works with HTD3M 3mm pitch and 6.35mm shafts - Handy for RepRap, delta printers, and small CNC setups
