Pocket Coaster – Print-in-Place, Folding Beer Mat

A compact, travel-ready coaster that folds up neatly thanks to built-in, print-in-place pivot hinges! It opens out to a full 100mm x 100mm square, then folds down to just 20mm wide. Bonus: It can also double as a handy phone stand!

🌀 Two Versions Included:

• Rounded Outer Edges – Classic coaster look when open.
• Fully Rounded Panel Ends – Sleek aesthetic when folded.

Zero assembly required—just print, fold, and go. Ideal for your desk, backpack, glove box, or pub table. Also makes a cool little EDC-style utility piece.
