How should I describe this part which looks like a small gear so that I can research replacements?

This came with my FLSUN 3D printer, which may be based on a Prusa design.

    $\begingroup$ Not sure I understand your question. It's the driven gear for the belt which either drives the X-axis or Y-axis depending on to which drive motor it's attached. Is that what you're asking? $\endgroup$ – Pᴀᴜʟsᴛᴇʀ2 Jun 27 '19 at 23:15
  • $\begingroup$ Thanks I just realized how unclear that was. I was asking the product name of this part. So that I could do my own research and find where to purchase a replacement. My 3D printer kit was missing one. $\endgroup$ – K Mmmm Jun 27 '19 at 23:19

This is a timing belt pulley.

Specifically, is a GT2 timing pulley, 2 mm pitch (between teeth), 6 mm wide. The drive diameter is measured by the number of teeth (16 in this case) , the shaft diameter (bore) is measured in mm.

The 'GT2' part refers to the tooth profile, some other examples are shown half way down this page.

    $\begingroup$ More specifically, it is a 16 teeth GT2 timing belt pulley. $\endgroup$ – 0scar Jun 29 '19 at 6:48
