This is a drink coaster with a microchip logo. Programming and microchips are cool!
This is a standard size coaster (100 by 100 by 5 mm), to fit in my coasterholder:
I have printed this model with Ultimaker white PLA. I used 0.2mm layer height and, 18% infill. I used a 0.4mm nozzle with my extruder at 210 degrees Celcius. I used a heated bed. To avoid the curling up at the bottom i used a brim. Don't hesitate to use your own configuration....no worries!
