Tape Measuring Tol

This handy tape measure add-on allows you to measure and mark with one hand. A 3D printed pencil holder attaches right to the tape measure body, and an arrow aligned with the pencil easily shows where the mark will a land. I made this with Tinkercad . This model will probably work with any tape measure, provided the clearance between the mounting opening and the arrow is wide enough.
