A snowball maker that presses an 80 mm ball and lets it go whole: two bowl halves on scissor arms, printed in place with no supports and no screws, plus a dowel for the hinge. The designer tested it through Alaskan winters; 0.12 mm layers keep the overhangs happy, and he publishes a heavier five-wall profile for hard-packed snow if you want this one built that way.
