Halbach Array Holder for NMR Spectrometer - Remix for K&J Magnets

thingiverse

A custom version of http://www.thingiverse.com/thing:942257 designed specifically for off-the-shelf magnets available from K&J Magnetics. Primarily intended to fit the BX066 1" x 3/8" x 3/8" N42 magnets with radially-aligned poles. These magnets produced a center field of approximately 0.4 Tesla. The magnet holes have been narrowed to create extremely tight tolerances, ensuring that the magnets remain stationary and do not rotate. A placement for a central magnet has also been incorporated. In previous experiences designing Halbach arrays, I found it significantly easier to insert and align outer magnets when a center magnet was already in place, aligned with the final magnetic field. The NMR sample holder has been enlarged and an *.stl file containing supports is now included. Although printing and testing have not yet taken place, they are scheduled to occur shortly.
