Designed with minimal tolerance fit. If it dosen't spin freely, throw in some abrasive and spin it around a bit.

Cover is designed to be cut out of clear polycarbonate and epoxied together. Stack/merge the 2 STLs for printing so it comes out as 1 piece. Seals to the housing with a piece of X60 or Ninjaflex filament cut slightly long so the ends press together.

Press fit magnets with glue, make sure they're flush with the surfaces for maximum coupling. Alternate
