20mm cube for walls test

It's a simple 20x20x20mm cube to test wall tickness and ajust flow rate.

After you set the e-step of your extruder correctly , you can fine-tune the flowrate for each filament pool with this cube.

The example is in Cura but probably any slicer can did it:

- Put infill to 0%.
- Put bottom layers to 0.
- Put top layers to 0.
- Set Wall Line count to 1 or 2.
- Print it.
- Do measurement with a digital caliper.

Measure the thickness of the wall with a digital caliper. The wall must be the size of your nozzle ( for example 0.4mm ) multiply by numbers of walls. If not , do this calculation and ajust the Flow Rate with this purcentage:

(AverageOfTheFourWallsThickness / (NozzleSize x NumberOfWalls)) x 100

Example:

Wall 1 = 0.36mm
Wall 2 = 0.36mm
Wall 3 = 0.34mm
Wall 4 = 0.34mm
Average = 0.35mm
Nozzle size = 0.4mm
Numbers of wall = 1

0.35 / 0.4 = 0.875
0.875 x 100 = 87.5%
