The phrase identifies a resource designed for physical measurement, specifically a template displaying units calibrated in millimeters, intended for reproduction on paper or similar media via a printer. The resulting printed instrument provides a tangible tool for determining the length or dimensions of objects in metric units. For example, a design for a 150mm straightedge, accurately marked, can be produced on a standard printer to enable measuring tasks.
Such tools are valuable due to their accessibility and cost-effectiveness, particularly in situations where a standard measuring device is unavailable or impractical. Their historical relevance lies in providing readily available measurement references in various fields, including education, crafts, and basic engineering applications. The accuracy depends on the printing process, emphasizing the need for calibration checks against a known standard.
The following sections will delve into the practical applications of these printable measurement aids, explore considerations for ensuring accuracy during the printing process, and review the potential limitations inherent in their use.
