Temperature Tower with Slic3r G-code generator

thingiverse

This is a fully customizable temperature tower in OpenSCAD that also produces G-code for temperature changes in Slic3r. To create your own tower, open the scad file in OpenSCAD, set the temperature range and step (which can go up or down), adjust model sizes to suit your preferences, and export STL. OpenSCAD will then print the G-code in its transcript. Clean up the ECHO and "quotes" so it looks like this: {if layer_z >= 1.5 && layer_z < 2.5}M104 S220{endif} {if layer_z >= 7.9 && layer_z < 8.9}M104 S215{endif} Paste into the "Before Layer Change" custom G-code window. Note that the base is printed at whatever temperature your slicer is set to, after which it sets the first temperature in the test range. In the example shown in the photos, the lowest temperature (180) failed completely. If you're unsure about where the end of the usable range is, make that the top end and start from a temperature you know will print.
