My tool is a band that has many functions. The 3D design comes with two bands, so you can wear them on your arms, legs, or waist. Instead of having a buckle, they have a double pull through design. The bands aren't just for wearing, but you can also add on weights that are designed to be like beads, going onto the bands. This way you can exercise while just doing everyday space duties. The material shown in blue on the band will be needed to be made out of a strong, flexable material. The two grey D - shaped parts would need to be made out of metal, to hold the band up and together. The bead-like pieces shown in red are the weights and will need to made in a heavy metal.
