***Buy it fully assembled & tested here! https://etsy.me/2U6v6ek The 'Geneva Roller Ruler' is a special pocket sized tool for measuring any line, any curve, any length! With this device you can measure square objects, round objects, straight lines, curved surfaces, you get the idea! **Additional Instructions & Photos here: (Take a sec to vote for this project too!) https://bit.ly/2uBcJPj This tool can be very handy when measuring curved lines or oddly shaped surfaces that are difficult to measure directly with a straight ruler or tape measure. The roller ruler uses a wheel of known dimensions, regularly spaced tick marks, and a counter mechanism to measure up to 1/2 meter in 5 mm increments. -The device is tiny so you can literally carry an infinitely long ruler wherever you go! :) It’s a simple but handy tool for home owners, architects, engineers, interior designers, fashion designers, decorators, art students, or anyone who needs to precisely measure irregularly shaped things on a regular basis. -A note on technical names: The intermittent geneva drive mechanism is also known as a 'maltese cross drive'. Technically this device should be called a 'curvimeter' ,'opisometer', or 'meilograph' Vitamins: 2x Screws: https://amzn.to/39MEoQN OPTIONAL: A badge reel is handy for making measurements & freeing your hands in quick succession and it also makes this a fun fidget toy too! :) https://amzn.to/2UhpFbO VIDEO DEMO: https://www.youtube.com/watch?v=S9XMkwvdbQU -If you make one go ahead and post an "I made this!"
