Simplify3d Extrusion Multiplier Calibration Cube

I made this because I needed to calibrate my extrusion multiplier and required a calibration cube with straight edges.

I do this for each variant of filament (e.g. brand and colour) and for each layer height I need.
I do this after I have printed a temperature tower to decide the optimal temperature to print the material at.

Steps to use:

Ballpark Extrusion Multiplier

1. Import the stl into Simplify3D.
2. Edit your profile and set the following:
a) Extrusion Multiplier = 1
b) Extrusion Width = Manual, 2 x normal extrusion width (e.g. for a 0.4 nozzle set to 0.96)
c) Primary Layer Height = desired layer height
d) Top Solid Layers = 0
e) Bottom Solid Layers = 0
f) Outline/Perimeter Shells = 1
g) Infill Percentage = 0%
h) Choose start point closest to specific location = X0 Y0
3. Save and print
4. Once printed let it cool and measure the center of each side with vernier calipers
5. Enter your measurements into this formula. 0.96/(
