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. Grab the STL file below and try it yourself, or follow along in this Instructable.
