Did a lot of renovations during the summer and one of the most frustrating experience was using the tape measure on a vertical wall, especially while on a ladder.

So I made a simple pencil holder that worked well, but had a few limitations, like the pencil was hard to be replaced or sharpened and also it needed a pointer for precise measurement.

In this video I'm making an improved version of it, from some scrap square tubing. It has all the features I needed, accurate pointer, release screw for the pencil and it can also use markers or metal scribers.
