Forearm Ruler Stencil

thingiverse

This is a stencil for a 10cm ruler you can paint on your forearm: Instructions: Preparation: A fine point sharpie and 20 cm of masking tape. 1) Put a piece of masking tape at each end of the ruler 2) Place the ruler on your non-dominant forearm and hold it in place with the masking tape. 3) Use a fine tip pen or sharpie to draw the lines, guided by the stencil. 4) You can use the cm section, the inches section or both! 5) If you use a sharpie, you can easily remove the ink from your skin with a cloth damped in Isopropyl Alcohol. Enjoy whatever DIY you do. I got this idea from Adam Savage, but I didn't feel like tattooing the thing on my arm: https://ar.pinterest.com/pin/355010383128196028/ About the design: - This is designed for the LEFT forearm, although it can be used on either arm. - The reason why the half-centimiter marks are closer to the wrist, is because I've found that part of the skin stretches and contract less, allowing better precision. - If you wear a wristwatch, you may use it to keep the ruler in place while painting the stripes, allowing you to clear the first markings away from your watch. - Version 3 has longer lines, version 5 has shorter lines for a less invasive ruler
