Really useful ruler

1. Not enough range
2. Inconvenient to use
3. Lanyard hole too small
4. Eat lotus root to recover from overeating

The main functions are:

1. 5CM measuring range, the measurement is longer, long, long, long, long, long, long, long
2. Add 0.5mm scale to make it more accurate
3. Added origin positioning, making measurement more convenient
4. A scale on the back is added to make the measurement more double-sided.
5. Optimized the lanyard hole for more comfortable measurement
6. Better looking, just better looking

The old rule, take photos of your talents

The white one is the optimized version, and the green one is the beta version.

I sampled two thicknesses: 1.0mm and 1.6mm. I feel that the 1.6 feels better and is very comfortable to hold in my hand.

After actual use, the experience of grid lines is a bit bad and will hinder reading. This thing has been removed in the official version.

The silk screen on the back is my personal logo, so I removed this part of the open source file. It does not affect the use but it feels ugly.

If you want a version with silk screen printing, you can contact me and I will give you one.

I think this silk screen is the soul. It takes five minutes to draw a ruler and a whole day to adjust the silk screen.
