Pasta roller: $13 brand new at Michaels
Small packages of oxyclean are the exact width of the pasta roller.
For a hopper I took my empty oxyclean cylinder, heated up a spot until I could stick the 2 liter bottle through, then I cut a slit on the bottom to better distribute the grain across the rollers.
I did heat ut up the bottom corner of the oxyclean tube to get a custom fit to the rollers. I just need to figure out a way to secure it in place!
