Stock Drive Products US https://sdp-si.com/  ?  ?  ?  ?  ? In the US, a popular source is SDP/SI. They sell a huge variety of belts and pulleys that meet our needs. Always call SDP/SI for stock, their website is always out of date.
  • Pulleys (bad link)
    Filter for GT2, 2mm pitch, then choose the bore size needed for your steppers.
  • Belts (bad link)
    Filter on GT2, 2mm Pitch, and get 2 belts as close to 1m long as possible.

Note, unfortunately, SDP/SI does not carry a smaller diameter GT2 pulley with a 5mm bore, so to buy your pulleys here you need a larger pulley than in strictly ideal. These are fine, though. I (Virtlink ?) use the 36 tooth pulleys on my printer and they work great.

Misumi Japan Misumi's pulley introduction  ?  ?  ?  ?  ?

Another good source for GT2 pulleys and belts is Misumi. They carry a huge variety of suitable pulleys, including several that are closer to out ideal diameter. In addition, Misumi has offices around the globe so they are a better choice for international customers (though some regions will only sell to businesses).

Their website does not make it easy to browse for belts and pulleys, but here are the relevent pages in their catalog:

Note: Misumi calls theirs 2GT (2mm pitch) and 3GT (3mm pitch). As far as I know they are compatible with GT2, but both offer the same benefits. Misumi's pulleys seem expensive, but they are metal pulleys. We don't really need metal pulleys for our needs, but they are fine.
