High Precision Test - Bolt & Nut v3

This is a "quick" (near 30min) high precision test designed to test and calibrate your printer for dimensional accuracy and elephant foot.

All the measurements can be found in the image.


---------------
### Procedure :
1. Check the bolt and nut height
2. Check the bolt base for elephant foot
3. Check the nut outer diameter
4. Check the nut top inner diameter (where there is no thread)
5. Check the nut top border width (where there is no thread)
6. Check if you can screw the nut, each thread has a 0.1mm tolerance


If you pass all the tests and you can screw the nut without effort you printer is awesome!

Extra step: Try to print it faster!!!
