3D printable ravioli rolling pin designed for use with home pasta rollers, such as KitchenAid stand mixer attachment. As designed, this roller produces raviolis that are 57mm square (2.25 inches).

• Designed as a parametric solid model in SolidWorks 2014 (source files attached). Feature sizes can be adjusted by editing the driving equations.
• Prepared for printing using Cura (ultimaker.com), and printed on an Ultimaker Original (ultimaker.com), with heated bed. PLA. 220C nozzle, 60C bed, "fast" printing profile. Between 6 and 7 hours to print. If so inclined, seal the printed roller with an epoxy coating, such as Smooth-On XTC-3D (amazon.com). I didn't bother.
• Ravioli dough and filling prepared as a variant of this Mario Batali recipe (foodnetwork.com). I like to use Antimo Caputo 00 flour (amazon.com). Some cooked and finely chopped sausage is also a nice addition to the filling.
• Dough rolled using Kitchenaid stand mixer (amazon.com) pasta roller attachment, starting at setting 1, and ending at 5, with a few passes at each setting.
• Per recipe, spread filling in thin layer across half of the sheet of dough, then fold the other half over the top.
• Press the roller across the top layer to form raviolis
• Trim using a ravioli / pastry wheel. (amazon.com), or better yet MEH4d's pasta cutter (thingiverse.com).
• Spread on a tray, and freeze, then store frozen in a ziptop bag.
• Enjoy!
