Abstract: The present disclosure relates to systems and methods that involve a plastic housing having a lower portion and an upper portion. The lower portion is configured to house a magnet that is adapted for placement above an electromagnetic assembly for levitation. The upper portion extends at least partially above the lower portion and further includes a slot. An elastomeric structure is disposed along an interior perimeter of the slot and includes a first plurality of ribs and a second plurality of ribs. Each rib includes a flexible portion and a retention portion. The flexible portion of the first plurality of ribs and the flexible portion of the second plurality of ribs receive an encasement and align the encasement in the slot. The retention portion of the first plurality of ribs and the retention portion of the second plurality of ribs secure the encasement within the slot.
