About this model

Most household sewing machines are designed for small bobbins and mini spools. Large cone threads don’t fit securely on the machine and the thread often fails to feed straight upward, causing uneven tension or snagging. This 3D printed Thread Bridge solves that problem by guiding the thread vertically before it enters the machine. How it Works The large cone spool sits next to or behind the sewing machine and the 3D printed bridge is placed on top of the machine’s spool pin. Two 3D model versions are available for 5 and 7 mm pins. The bridge can be placed in multiple ways so it will fit and work in your situation and the thread passes through the smooth guide eye at the top of the bridge, ensuring a perfectly vertical feed. This prevents jerking, snagging, twisting, or sudden tension chang…
