Hollow Squid game's Gonggi

This is a remix of the "Accurate Squid Game Gong-Gi" model, with the following changes: larger internal cavity. The problem with most Gongi models is that they are made of plastic filling, which makes them light, difficult to handle in-game, and prone to bounce. To improve playability, the Gongi should be heavier and less prone to bounce. With this design, the idea is that the user can pause the print halfway to introduce heavy material into the cavity (sand, nuts, pebbles, etc) and then resume printing, obtaining high-weight, low-bounce Gongis with an impeccable result.
