I used my 3D printer to make it, but if people are interested I might make one out of stuff everyone can find.

#Print to scale ruler how to

In this instructable I'll show you how to turn a ruler into a caliper. Plus, I figured that if I made a CAD model I could make a left-handed version too! You guys are always forgotten, but not anymore! Also, by using adding a Vernier scale I could reach a resolution of 0.1mm. I figured that if I base my caliper on a ruler, which is super cheap and 100% reliable, I could end up with a very reliable caliper. For those of you who are unfamiliar with what a caliper is, it's a tool that is most often used to measure out/inner diameters of objects, and there are more than a few instructables on how to use them. After I was done mourning over my 20$, I decided to make my own. Spent 20$ on it, and it's completely worthless - totally unreliable.

This procedure seems somewhat cumbersome, however once you have mastered it and understand it's principle, you will be quickly and easily converting scale drawings to real measurements with no math involved. Take the reading from this part of the scale (depending on the scale this may be graduated smaller or larger than 1') and add this number to the whole feet you mentally noted earlier. Now if you go back to the zero end of the scale the fractional feet to be measured will be represented by the distance of the start point of the object being measured to the zero point on the scale. Then slide the ruler so that the number you noted mentally lines up with the end of the item being measured.

This number represents the whole feet of the item you are measuring. Mentally note this number and be sure to 'round down' even if you are close to the next number.

Read the number off the scale that is closest to the ending point of the item measured. Line up the zero mark on the scale selected with the beginning of the item you wish to measure, then determine at what point on the scale the end of the item you wish to measure is. One scale reads left to right and the other right to left. Be careful when selecting the scale on the ruler, there are two scales on each edge. This would represent a drawing with a scale of 1/8' = 1 foot. For example, 1/8 on the ruler is in fact a scale that converts 1/8 inch on the drawing to 1 foot. Once the scale of the drawing has been ascertained, select the correct scale on the ruler. Most architectural, construction and engineering drawings and blueprints are scaled to allow for large areas, structures or items to conveniently fit on a reasonable size of paper.Д«efore using an architect's scale or ruler, it is important to know the scale of the drawing or item that is being measured. An Architect's or scale ruler is designed for use in determining the actual dimensions of a distance on a scaled drawing.
