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.
