About this 3D model

Are you like me when designing things? It turns out I'm really bad at ballparking sizes and having an actual feel for what makes sense. I start drawing and pick a size that feels good, only to print it and realize it's way too small, or big. So, I decided to make a simple too to have at my desk to give me a quick sense of scale. This smart ruler gives you: Millimeter distance 0-20cm (for lefthanded use) Relatable hole sizes starting at .5mm in steps up to 20mm Relatable at-a-glance sizing starting at .5mm in steps up to 40mm Angles of 15, 30, 35 and 60 degrees.
