This is a Momo dumplings maker. It's suitabe for 3d printabe and iinjection mold making.

History of Momo dumplings:It is believed that momos originated in Tibet and were introduced to Nepal by Tibetan immigrants who settled in the Kathmandu Valley. Over time, momos have become an integral part of Nepalese cuisine and culture, particularly in the Kathmandu Valley, where they are often served during festivals and special occasions.
