For the Delta Flyer's maiden voyage, I opted to go cheap and use Prime Line rollers (referenced in an earlier log). They're fairly inexpensive and I didn't have much grief finding them at a couple different local stores. They definitely have slop in them, so they're not really a good choice and probably go from rough to terrible as print speed is increased. Episode II here is to illustrate how well these actually work.

• STLs used came from here
• An example of the M-6002 Tub & Shower rollers
• Assembly Instructions (Use 8-32 bolts & nuts)

I found that I could get passable motion. I ultimately replaced the Prime Line rollers with Delrin rollers. I was stunned to find the first prints out of the Delrin's looked exactly the same as the Prime Line wheels. This led to eventually find my main source of error was my print bed could move during the print. Therefore, I'm not really sure what the quality limit on the Prime Line rollers really is. My guess is you could get pretty damn good but if you tried to print fast, the slop in the bearings would become intolerable.
