NOTE: If you like regular/smaller dumpling sizes, print the original! (on the left there).

This is the same as the very well-done dumpling press made by @Oggie (please give him credit!), but I just took the interior filling/circular area, and scaled it out, so that the edges are smaller/less wide, and there's more space in the center for filling. Cheers, and thanks Oggie ;-)

My pic of the dumplings could be better... first time in a while and the dough wasn't great :-]

Print it with at least 5 perimeters, 20-25% infill, otherwise it may break when trying to free the hinges after printing. Similarly, nozzle should be .4mm and layer height .2mm or less.. otherwise hinges can't break free as easily.
