Pokemon themed squid games gonggi.  Two designs are included: weighted and solid fill.

Option 1: 

The weighted gonggi was design to use a ¼" X ¼" tungsten weight (pinewood derby weights).  A pause in the print profile allows you to slide in the weights.  If the weights you receive are too big, a drop of super glue can be used prior to sliding in the weights to prevent rattling.  

This design utilized the ruisita 3 ounce tungsten weight cubes.  Total weight for 5 gonggi is around 44 grams.

Option 2:

For those who may not want to use weights in the gonggi, a solid fill design is also provided (plate 2).  The solid fill design will come in around 18 grams.
