Assuming 5mm pitch (GT2 or HTD), that's a 28T pulley. 1.754" PD, 1.875"
Flange diameter (per sdp-si spec). Just posting this so people have a data point to compare to.
I'm really surprised by a 1-7/8" flange on a 2" wheel. That flange is DEFINITELY touching carpet from my experience, but since the traction portion of an octonum is so rarely used I can see that not being a big issue (especially if metal flanged pulleys are used).
For future reference, I bet the c-c is small enough that if there is a flange on the pinion pulley and the belt is reasonably tight no flange is required on the traction wheel pulley.

3" is MUCH too big for a butterfly
