Mail Organizer Box – Dual Slot Letter Holder

Keep your mail under control — even those bills that keep mysteriously appearing.
This dual-slot mail holder is designed to neatly organize standard letters up to 12.5 cm wide, making it perfect for everyday mail, invoices, and documents.

The main body is easy to 3D print and optimized for PLA, while the Voronoi-pattern side panels are printed separately, allowing you to add a second color for extra style. The side panels are glued onto the central body after printing, keeping the print simple and clean with no supports required.

With its modern Voronoi design and practical layout, this organizer turns your mail pile into an orderly stack — because if you’re going to collect bills, at least do it in style.
