Piggy lightswitch pull-cord thing

thingiverse

This design is ideal for a lightweight cord that requires minimal bulk. To achieve a thicker cord, simply scale up the dimensions accordingly. The main ball measures 3.5 cm in diameter, with a hole at the top that's approximately 3.5 mm in size. To print this object successfully, use a low layer height of .2 and four shells for added stability. A sparse infill will help reduce material usage while maintaining structural integrity.
