I scaled up brandonh's carriage that was sized for the Dual 623 V roller and made it right for some M-6153 Prime-Line tub and shower rollers I got at Lowes.
This option cost me about $10.00 for the rollers and saved me some serious cash to get the machine printing.
I will warn you that these rollers have some slop in them and if you have the cash you might go with some more expensive options though my print quality is quite good so I will stick with them for a while.
