The ONE 3 from TA+d is a multipurpose EDC (everyday carry) scale ruler that does everything from taking accurate measurements to drawing detailed designs. The tool is made with sturdy Aerospace-grade aluminum to ensure durability and precision and is capped at either end by non-slip rubber tips. These tips allow the tool the be used in place of hands for contactless interaction.
The ONE 3 comes equipped with a 2.0mm clutch pencil housed in the center of the tool and secured by a magnetic locking mechanism. The pencil, which writes like a pen, has erasable ink that works with the tool's eraser tips to maintain efficiency throughout projects. In addition, the ONE 3's 168mm scale is calibrated for both the Imperial and Metric systems for ease of access. The ONE 3 can be acquired through its already funded Kickstarter campaign.
