The first puzzle unit assembly includes a first support member and a second support member projecting from a first inner surface of the first unit assembly, and a first triangular unit face on an outer surface of the first unit assembly. A space between the first support member and the second support member define a first linear slot. The second puzzle unit assembly is geometrically identical to the first unit assembly, including a third support member and a fourth support member projecting from a second inner surface of the second unit assembly, and a second triangular unit face on an outer surface of the second unit assembly. A space between the third support member and the fourth support member define a second linear slot, with the second unit assembly rotated relative to the first unit assembly such that the second linear slot aligns with the first linear slot. A portion of the first support member overlaps with a portion of the fourth support member, a portion of the second support member overlaps with a portion of the third support member, and a common edge defines an angle of about 60° between the first unit face and the second unit face. The third removable unit face engages with the first support member or the fourth support member such that the third unit face occupies a plane substantially parallel to planes occupied by overlapping first and fourth support members. A fourth removable unit face engages with the second support member or the third support member such that the fourth unit face occupies a plane substantially parallel to planes occupied by overlapping second and third support members. ## Claims ### Claim 1 A first puzzle unit comprising: a first puzzle unit assembly including a first support member and a second support member projecting from a first inner surface of the first unit assembly, and a first triangular unit face on an outer surface of the first unit assembly, with a space between the first support member and the second support member defining a first linear slot;
