  02/06/26:

  Purchasing 6mm rod and bearings, torsion springs, and the hall effect sensors (A1324) for high sensitivity

  Updated the CAD to account for insets for bearings as well as different test locations for neodymium 52 magnets! Still need to add some sort of inset for the torsion spring end (need to learn more onshape skills + intuition for this)

  Something to think about: the current magnet insets are 2mm and the magnets are diameter 6mm with 2mm thickness, but I'm wondering if the inset into the key needs to be reduced so that the hall sensor can actually detect the field and experience more fringing/exposure to detect changes in the magnetic flux.
