Dough cutter with detachable rolling blades for making Russian dumplings. You can use the 6 cm blade to cut circles for pelmeni or the 7 cm blade for vareniki (pierogi). I printed the blades by supporting them from the print bed and oriented them upright.

UPDATE (October 18, 2021): Added some new thicker blades (5, 6, and 7 cm). Early I suggested printing the blades upright but then turned out this orientation is not optimal. So, try to print them horizontally, in my opinion, that gives the best print quality.
