I ordered some before coming here and seeing that others were interested in a group buy. Last night, I downloaded the files from Thingverse and then printed them via treatstock.com. Six sets were $5.49 (+ $4.02 shipping). They're shipping to me today. I imagine that they'll be here in a couple of days and will post a review.
Looking forward to seeing how they work for you!
