Little Star 5/8" Marble Cage

thingiverse

This is a two-part assembly that clicks together to form a marble holder for a 5/8-inch marble, featuring a hole for hanging. For marbles of a larger size, like 7/8 inches, there's an alternative design available online. Marbles are not manufactured with exact precision, so use calipers to measure yours accurately. If the marble is slightly smaller than the holder's specifications, it will still work fine. However, if it's too large, the parts may not snap together properly when made with SLS materials or might break apart when using more brittle materials.
