Recommend filament for replacement and upgraded parts

@KTMDirtFace this is a prime example of where most people would blame the slicer and then recommend S3D, but you already use S3D so that is just more proof it is settings and calibration more so than what slicer you use. I know you calibrated your printers so mechanically they are likely pretty close, now it's time to fine tune the slicer settings.
