Roller Time Machine

• No support required
• No accessories needed
• Snap-fit design, ready to use with a twist

Centered around a retro mechanical roller structure, this calendar breaks down months, dates, and weekdays into separate rolling modules. The manual twist mechanism turns date-switching into a fun "time-toggling" interaction. The red-and-white color scheme retains the classic visual of vintage calendars, while its sleek modular design fits modern desk setups. It’s both a functional date tool and a desktop trinket that blends mechanical texture with nostalgic charm.

Just a heads-up: There's an issue with the numbers in this file. Please adjust them yourself before printing—I don't have time to fix them as I'm off on vacation. I'll sort it out once I'm back.
