Need a display stand for that special cube? Try one of these wood stands. The small version can easily hold up to a 3" cube and is about 2" across the sides. The large version is about 2-3/8" across the sides and would hold a cube up to 3-1/2" and possibly larger depending on the pieces in the cube. (No requests on the surprise me version please) and since these are made from leftover pieces of wood, thickness may vary slightly.
Approximate Size: Small - 2" (5.1cm), Large -2.375" (6.1cm)
