This print cycles through every combination of filaments in the minimum number of changes.

You can use this to test your flushing volumes, or set a low modifier like 0.25, then measure the bleed and adjust where needed to find the minimum flush volume that eliminates bleeding. I used this on a 4-day. print to reduce the print time by 12h and significantly reduce waste

The objects are scaled so that every 1mm of print height = 30mm3 of filament. So if the filament bleeds 1mm into the next section, add 30mm3 to that flushing combination. If you want to be really precise, every 0.20mm layer is 6mm3.

Select the plate based on how many filaments you want to test (4, 3 or 2).

Keep whichever shape you want enabled and disable the other in the Objects window (cylinder or box).
