What was this for, Walter?

I'm using them on my Eustathios printer, for the flying extruder - http://thrinter.com/cartesian-flying-extruder/. I was using some metal ones that I had bought previously, but all the grooved pulleys I tried had low quality bearings and were noisy. These are working better, they're tall enough to wrap the 2mm shock cord around the pulley twice.

Awesome! I thought you ditched the cartesian flying extruder for the direct drive setup?

I saw this and thought it looked good for a counterweighted flying extruder for my new Delta (using latex tubing or the like).

No, there was too much ringing with the direct drive setup. If I was building another Eustathios, I'd try one of the lighter direct drive extruders, Bondtech BMG or E3D Titan/Aero, but it's been working well so I haven't felt the need to change things.
