Would you like to test your new filament's temperature range? This temperature tower is ideal for you.

It is fully customizable - width, depth, number of elements, text embossing, etc.

Just open temptower.scad in OpenSCAD, modify properties as you want. Render it (it takes some time), save it as .STL.

Open .STL in your favorite slicer, use always the same layer height (e.g. 0.2mm), slice it and save G-CODE somewhere.

And run Python script tempinjector.py with the corresponding parameters, e.g.: python tempinjector.py tt.gcode tt.modified.gcode 250 -5 5.0

This simple script replace and add new extruder temperatures to the g-code at appropriate levels.

Just print modified g-code file.

Tested with Slic3r and Repetier.
