Parametric temperature tower with Slic3r support

pinshape

This is a fully customizable temperature tower in OpenSCAD that also generates the G-code for temperature changes in Slic3r. To create your very own tower, simply open up the scad file within OpenSCAD, set the temperature range and step according to your preferences (you can choose to go either up or down), adjust model sizes to suit your taste, and export STL. OpenSCAD will automatically print out the G-code in its transcript. Clean up any ECHO statements and unnecessary quotes so it looks like this: \n\n {if layer_z >= 1.5 && layer_z < 2.5}M104 S220{endif} {if layer_z >= 7.9 && layer_z < 8.9}M104 S215{endif} \n\n and paste into the "Before Layer Change" custom G-code window. Note that the base is printed at whatever temperature your slicer is currently set to, after which it sets the first temperature in the test range. In the example 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 successfully. Note that the SCAD file has been renamed to tempTower_scad.txt - rename it back to tempTower.scad. The .txt file contains the Slic3r G-code corresponding to the included STL. It's generally okay for most PLA, but in general, you'll want to generate your own STL and G-code from SCAD.
