Magnetic Coasters | Auto-Aligning & Support-Free

🌟 Feature List
 

Auto-Aligning Magnetic Stacking: Uses four neodymium magnets (D4xH2) in a rotated-square layout with alternating N-S-N-S polarity to automatically snap coasters into perfect alignment.
 

Advanced Condensation Management: Features an outer retention lip and an inner reservoir groove to catch runoff and prevent table rings.

Anti-Suction Technology: Recessed radial air channels on the underside break the vacuum seal, preventing the coaster from sticking to the bottom of wet glasses.
 

Glass Centering Ring: A slightly raised inner ring naturally guides glasses to the center of the coaster.
 

Ergonomic Fluted Holder: A parametric, symmetrically fluted holder featuring an extended thumb-notch designed for easy stack removal by both children and adults.
 

Anti-Tip Ventilated Base: The holder incorporates a weighted base ring for stability and a hexagonal honeycomb cut-out for airflow and moisture evaporation.

100% Support-Free Printing: Designed to print completely flat on the build plate with zero overhangs or supports required (recessed bottom text and channels).
