Stihl weed whacker bump knot. Replacement head for FS-45 and other models listed. This part kept wearing out on my weed whacker and I got tired of paying $25 for it. You do need to STOP the print right before the top closes in, (I used a "color change") in order to drop the nut in place. Fits Stihl FSE60 FS38 FS40 FS45 FS46 FS50. Part # 4006-710-4000 If you use the Gcode file it will stop and ask to change the filament for a color change. That is where the red filament comes in. On that stop is when you drop the nut from your old cap in. It took me 10 attempts to get this drawing right. Enjoy.
