Model Overview

This ROKR Perpetual Calendar is a hands-on mechanical model and 3D wooden puzzle that assembles into a working perpetual calendar. It blends clever gearing with a natural wood finish to create a display piece that also performs a useful function: set the year and month and the mechanism shows the day of the week. Ideal for hobbyists who enjoy practical, moving models, it makes an eye-catching desk companion.

About the Manufacturer

ROKR DIY models are delivered as laser-cut plywood kits. Components come on frames so parts pop out cleanly, and the pieces are designed for durability and an ecofriendly presentation. The kit includes English instructions to guide assembly.

Subject Background
