The frog’s name sounds like “gua,” which conveys the auspicious meaning of “top-notch” or “outstanding”; meanwhile, the act of striking it carries modern psychological associations with “accumulating merit” and “alleviating anxiety.” The frog-shaped wooden fish (or the small mallet held in its hand) is a typical overhanging structure that requires support structures—tree-like supports at 15% infill density are recommended—otherwise the tip may sag or the print may fail altogether.
To achieve optimal sound quality when striking and maximum structural strength, vertical printing is recommended (with the frog in a seated pose). If printed horizontally, the layer lines will become weak points under stress, and vigorous striking could easily cause cracking along these layers.
