Dual Yarn Spinner (Ball Bearing + Sand Filled)

Stop chasing your yarn balls across the floor! This Dual Yarn Spinner is designed to keep your yarn tangle-free and your tension even while you knit or crochet.

Unlike lightweight 3D printed holders that tip over, this design features a hollow base intended to be filled with sand. This gives it significant weight, ensuring it stays completely stationary even when you pull on the thread firmly.

✨ Key Features:

• Dual Spindles: Perfect for colorwork, holding two yarn cakes at once.
• Ultra-Smooth Rotation: Uses standard ball bearings for frictionless spinning.
• Heavy Base: Filled with sand during printing (or assembly) to prevent tipping or sliding.

🖨️ Printing & Assembly Tips:

• Sand Filling: This model is designed to be weighted. Remove as much supports as you can from the inside and then fill it with sand. Use the plug and glue it together to close the hole at the bottom where the sand was filled in.
• For assembly, put the Ball bearing on the screw, then the disc with the raising towards the bearing and then screw it into the rod
