Pasty / Dumpling maker

Roll 2 party pasties, dumplings or anything else you desire, at a time.

Hardware needed:

2 x 3mm screws, around 15mm long
1 x 4mm wide spring @ 50-55mm long for the sprocket
2 x springs (optional) for the ends of the rollers to keep them together so they don't spread apart under pressure

Note: If you can make this better, I would be interested to see remixes.
