Description : This non-millable six piece burr is surrounded by a cage split into two mirrored halves. Not only must the solver figure out the burr itself, but they must also understand the burr within the constrains of the cage.

While the pieces are symmetrical (two pairs of mirrored sets plus an outlier), the solution is decidedly non-symmetrical. There are several interlock...
