The Purge Coaster is a way to make custom multicolor coasters that utilize purge waste (or printer poop) as the inside colors and your choice of filament for the outside color. This has a fairly forgiving thread to screw the top on.

102.42 mm or approximately 4 inches in diameter.

My two young children loved organizing a bucket of various purge nuggets into piles of different colors to help me with this. I hope you can have fun making your own.

I recommend you choose contrasting colors for better visibility.

Print settings:

Printed in Bambu PLA Matte White.

Note: Print in PETG if concerned about high temperature cups or mugs deforming the print, but the purge nuggets in the middle should provide some support to the hexagon pattern.

0.20 layer height

Print the Top piece with the hexagons on the build plate

Turn on “Avoid crossing walls” in BambuStudio or similar setting in your slicer of choice.
