GT2 2mm Pitch
This is a GT2 2mm pitch timing belt, by the hobby roboticist: Skyentific
Reasoning for choosing this belt: if its good for him it will be good for us.this is what 3d printers use, so lots of places to find belts and small pulleys
Reasons for not choosing this belt: hard to find big pullies
