Thread and Bobbin Holder

This holder is designed to hold thread spools and bobbins together. The large circle has several rings that friction fit on several different styles/brands of thread spools. They have been tested with Isocord, Glide, Finess, and Aurofill. It probably works with others as well; there are 3 basic spool designs they all seem to use. The smaller circle is for bobbins and should fit any design, we've tested generic bobbins and several brand specific. Printing Tips You can print the first few mm to test the fit with your spools. I designed this to print on our Bambu X1C, your final dimensions may vary a bit with your printer and filament. You'll want to have well dialed in retraction to avoid stringing between the two vertical posts; too much stringing will change the diameter so it won't fit the spools anymore. The vertical posts rely on good layer adhesion for strength, so you might want to avoid matte colors and other filaments where the layers aren't as strong.
