Cross product direction finder

thingiverse

This device aids you in locating the direction of the cross product (or vector product) of two arbitrary vectors without resorting to manual manipulation with a right hand rule, making it especially beneficial for students working with torque or magnetism in math and physics classes. The product comes apart into two sections that interlock as a hinge; no supporting elements are needed. To work effectively, an infill percentage of 50% or more is recommended. Instructions to Use Make adjustments if desired. To suit my specific needs, I use numbers one and two for the vectors involved, so you might consider using other identifiers. Print both pieces, which can be printed together or separately, using an infill density of at least 50%. The choice of material, including PLA plastic, does not greatly impact performance. My own tests were conducted with a layer height of 0.150 mm between layers but varied settings could yield satisfactory results as well. To assemble the device, slide one rod from the base section through the hole at the end, ensuring numbers one and two align facing up. Carefully insert the remaining piece into its designated hole on the opposite end. A key or flat tool might be necessary for achieving a secure connection. If desired, emphasize text (such as "1," "2," and "1x2") with colors. White-Out or markers work well for achieving visibility.
