When your building a project, you'll often need a few bits and pieces of hardware such as heatsinks, screws, standoffs, or other materials such as copper tape.
Couplers / Collars
If you're connecting shafts of two different sizes or even two of the same, you'll need a coupler to join them. be sure to pay attention to the Imperial vs. Metric sizes.
This is a small selection of our maker favorites, if you're after more options, check out our full range of Couplers and Collars.

Gearboxes
We've got different configurations of gearboxes to suit any project, however, bear in mind that these are plastic gear boxes, perfect for high speed, low torque, but for high torque applications where a lot of strain is being placed on the gears, you'd be better off with a metal gear motor.
