Prints every part-cooling fan speed in one tower, so you can see which setting a filament really needs.
How to use it
Start a new, throwaway project and select your printer, filament and nozzle.
Run Plugins → Calibration → Fan Tower.
Set the fan range (default 0–100 %), the number of bands (default 5) and the band height.
Slice and print.
Enter the winning value in Filament Settings → Cooling.
Reading the result
Look at the thin pillar first. The head travels to it every layer, so it barely cools and shows problems before the tower does.
Sagging overhangs, bulging corners, fused layers: too little cooling.
Pick the lowest speed that still looks clean. More cooling past that point only costs layer adhesion. PLA usually wants the top of the range, PETG and ABS much less.
Good to know
Each band's fan speed is engraved into its front face.
To stop PrusaSlicer's automatic cooling from overwriting the bands, the plugin turns off auto cooling and the fan ramp-up in the project's filament settings. It does not restore them, so use a throwaway project.
Adds a 5 mm brim so the slender pillar stays on the bed.
Runs fully inside PrusaSlicer's plugin sandbox, with no network access and no files written.
Changes in this version
Fixes the placement of the band labels and the cooling pillar, which could end up offset from the tower.
