Circle Drawing Templates - SAE & Metric

thingiverse

I created circle drawing templates because they contain surprisingly large circles for such small templates (2" and 50mm) and they are very compact. Have you ever used a jar lid to draw a larger circle? One template is SAE (Imperial) and the other is Metric. They can be used with pencils, pens, felt pens, and even Xacto knives if you are careful. Here are the circle sizes for each template: SAE 3/8" 1/2" 5/8" 3/4" 1" 1 1/8" 1 1/4" 1 1/2" 1 3/4" 2" Metric 6 10 12 15 20 25 30 35 40 50 mm Each circle's outside border diameter can also be used for drawing curves. The SAE circle template's outside border is 0.2" larger in diameter than the inside diameter shown above. The Metric circle template's outside border diameter is 5mm larger than the inside diameter shown above. This means that each compact drawing template contains as many as 20 different curves. They are small and easy to print. They are 2mm thick. I printed mine in PLA on a HyperCube 3D printer.
