Printing and slicing

Make sure that seam on the lower cylindric surface is in the prepared groove. Slicer should put it there by default. Otherwise a print seam that is protruding out  is going to slightly misalign the piece in the focuser. 

I recommend dark/light/dark fillament scheme on the Cheshire piece to get better view contrast on the crosshairs.
