A winter themed snowflake cup coaster.  I print in PLA. At 0.2 mm layer thickness, it's 20 layers thick (5mm total).  I start the print in royal blue and pause after layer 15 finishes.  At that point I switch my filament to bright white and complete the print.

Details:

Diameter: 105mm

Printed at 0.2mm layer height, 20% infill
