.4 or 5 series purple protector kit Not for silver bobbin machines Not an endorsed Bernina Product B43

So grateful for the protection this little 3D printed piece provides for my Bernina 590. I had the great misfortune to accidentally brush against my machine as I was moving it from my trolley to my table...and POP! The stitch width regulator knob was rolling on the floor. Because of the way this beautiful little machine is made, you have to open her up to replace that little knob. For the bargain price of $165, my favorite local authorized Bernina repair shop was able to replace the knob. Just think of all the notions, fabric, or projects I could have purchased with that same $165! Trust me...the $20 I spent for the knob protector set is well worth it! Thanks Jeff!

Works great

They fit perfect and love the colors.
