Seven Triples puzzle

thingiverse

Seven distinct shapes are available, with three identical copies of each shape. The shapes tend to group together in sets of three. Can you arrange the seven sets so that for every possible pair of shapes, there is exactly one set containing both? Initially, disregard color variations and focus on grouping by shape alone. Once grouped by shape, rearrange the sets to ensure each contains a piece from each color category. The design of these pieces was crafted using Blender 2.8 software. Print three identical copies of each piece in different colors to facilitate this arrangement.
