Wanted: 70mm sprockets & PTRs.

[Natalie Gooch]

I'm looking to upgrade to real 70mm sprockets & add particle transfer rollers to my scanner. Lavezzi's 16t 70mm sprocket (#716C25K) would work great, but I can't seem to find it anywhere. I found a source for 70mm PTRs but their minimum is 6, and I only need 2.

Thanks for any help and guidance, I'm a bit new to the professional side of things I designed & 3D printed almost everything in my scanner, and the plastic sprockets are not tight/reliable enough for what I want to do.
