Flow calibration cube

Another .8 flow cube with an open top and bottom for a .4 nozzle.

Print out and measure side thickness to determine if your flow is accurate.

Print it out in ,2 resolution that should allow you to print a double thick wall line. Add the measurements of all 4 sides together, and divide by 4. The double digit number should be your flow percentage to use to obtain the perfect flow rate.

Tweak accordingly and re-measure until right.
