Tour de température et de pontage personnalisable tout-en-un

Create your own temp tower with OpenSCAD. NO programming skills required!

Update 6-1-2024: Changed custom Gcode to address floating point calculation issue (inline pics in instructions don't match the new gcode). Kudos to @StefanPohl_1942191 

My “Improved All-In-One Temperature and Bridging Tower” is very popular but sometimes you don't need to check the whole temperature spectrum, or maybe you want to check in steps different than the default 10 degrees C of most temp towers.

So… here's a fully customizable version, for use with OpenSCAD!

Uh… OpenSCAD? What's that?! Do I need to learn how to write code?

No, you don't! It's actually very simple, and you don't need to “speak SCAD” to build your very own temp tower.

Here's a step-by-step guide:
The preliminariesIf you don't have OpenSCAD, it from https://openscad.org/ and install it following the standard installation procedure for your computer platform. the .scad and .3mf files from the Files section and save them somewhere on your computer. Let's create the temp tower modelLaunch OpenSCAD.Use File>Open File to load the ed “Customizable Temp Tower.scad” script.You should see the Customizer on the right. If not, go to the Window menu and uncheck Hide Customizer. Also, make sure Hide Console is unchecked.Select the appropriate options (see below). If needed, press F5 or go to “Design>Preview” after you've made changes, to update the image of the model.When you're happy with the results, press F6 or go to “Design>Render” to render the model.  Rendering may take some time, so please be patient. Watch the progress bar at the bottom right of the window.When rendering is complete, scroll up in the Console pane until you see “Insert the following lines…". Use your mouse to select the lines starting with “;AFTER LAYER CHANGE” up to the first blank line. Right-click and copy them. (Ctrl/Cmd-C doesn't seem to work).Press F7 or go to “File>Export as STL” and save the model as an .stl file.  Now let's set up PrusaSlicerOpen PrusaSlicer. You may use the attached .3mf file as a starting point, or start with a blank slate.Load the .stl file you generated from OpenSCAD. If you're using my .3mf file and did not change the default name of the .stl file, just right-click on the model and select “reload from disk”. Select the appropriate print, filament profile, and printer profiles.Make sure you're in Expert Mode (upper right corner):Go to the Printer Settings Tab (Ctrl/Cmd-4)>Custom G-code, and go to the box labeled “After layer change G-code”. Delete the two lines that are in that box by default.Okay, let the magic happen…
We have to tell PrusaSlicer to change temperatures at the appropriate points. We use custom G-code for that purpose. 
In PrusaSlicer, paste the lines you copied in OpenSCAD into the “After layer change G-code” box.That's all! Switch back to the Plater view, slice, save, and print.OpenSCAD customizer options
The customizer offers several options for adjusting the model. Most are self-explanatory. 
Under Main Options, first enter any text to describe your filament type (PLA, PC, ASA, etc). Next, select the highest temperature you'd like to test with your tower.  This will be printed first. Then define the temperature steps (decrease of temperature PER tier) of the tower (in Celsius), e.g, 5 or 10 degrees. Finally, set the number of tiers to use in your very own temp tower.That's pretty much all. However, if you have a long name for your filament, you may want to go to Other Options and change the gTypeScale scaling factor so that the text fits properly onto the tower's base. Still, if it's too long—like “some weird and exotic filament”—, the text may end up being too thin to print properly. Sorry, nothing I can do about that.Update 7-2-22: Under Other Options you can now add the filament brand to the top and/or bottom of the tower. Just type the name into the gFilamentBrand box and adjust the size as needed with the gBrandScale slider. Text on top will be raised, text on bottom recessed.Version History
Update 8-17-2023: Added If statement to custom gcode, to make sure top layer is printed at same temperature as block below, per Eug_11697.

Update 7-18-2023: Fixed inverted protrusions, per @k2e2ni's code. 

Update 7-2-2022: Per @rayanth's request, I added an option to put the filament brand (or ANY text) on top and/or bottom of the tower.

Update 6-26-2022: Kudos to @Netfool for coming up with a method to generate custom g-code right in OpenSCAD (see Comments section)! Added his code to the script and updated the instructions accordingly.
