5T3S

 

This is a set of 24 sticks in two lengths.  The woods shown above, from lightest to darkest, are holly, madrone burl, purpleheart, and zircote.

Three short sticks and three longer
sticks connect as shown:

European Beech

Four such compositions of six sticks can interlink to make the 5T3S assembly:

In a variation on this assembly, the magnets are eliminated and the sticks are glued together in groups of three.

Quite challenging to put back together, this type of assembly is called a coordinate motion puzzle.
