Works with standard 4.5mm beaded chain from hardware stores, so you can build or fix your mechanism without custom parts.
Designed for Z-axis drives on RepRap 3D printers, so your print bed moves smoothly and reliably.
Prints in durable PLA, giving you a strong gear that handles repeated use without wearing out.
Fits CNC machines and general drive applications, so you can use it for many projects beyond just printing.

You need a gear that works with materials you can actually find at the hardware store. This beaded belt gear connects to standard 4.5mm ball chain, so you skip the hunt for specialty parts and get your project moving today.

Built for RepRap Darwin Z-axis drives, this gear handles the up-and-down motion of your print bed with precision. The tooth design grips the beaded chain tight, so there is no slipping during long print jobs. You can also use it for CNC mechanisms and other drive applications where you need reliable power transfer.

When you print this gear on demand, you get exactly what you need without waste. The PLA material prints strong and lasts through countless cycles of use.
