Designed for 350mm x 350mm or larger bed, will print smaller but may go from crown to tiara. Originally printed on a Creality K2 Plus This is a bit of a dirty file that needs a large bed printer to print full size. No Supports because you print flat and then shape to the wearer. After printing, remove and place back on the bed. For PLA, raise bed temp to 100C to soften the print. Other materials may need different temperatures to mold properly Carefully remove the print and shape to size. If you shape the bottom, the top will generally form to the correct shape. Hold in place until cool to retain the new shape. A small fan can assist in the cooling. If you mess up the first time, you can use any of the standard methods to resoften the crown and shape again.
