In honor of The Wolverines winning the 2023 College National Championship I designed some drink coasters. I ususally print them face down on a smooth pei plate. If you print them face down change the print order to blue/yellow/white. I think that way comes out the best. I Included some holes to insert some 10mm x 3mm magnets which keep them stacked neatly in the holder. Just make sure the magnet polarity is the same on each coaster.
