The final product incorporates feedback from all of the prototypes. A total of 8 different timber species are included to allow the students to experiment with different weighted blocks as well as learning about the properties of different species. The hole pattern is maintained over four different block sizes and a larger quantity of blocks and dowel are included in the kit. The quantity of each timber species that is included in the kit correlates to the quantity of that species of timber that is used in the industry. Larger quantities are provided of the more common species, such as Radiata Pine, and fewer blocks are provided of the rarer species, such as Sassafras and Huon Pine.
