Stringing Test

thingiverse

The presence of small strands of plastic on areas where the print head should not be printing indicates stringing, a common issue in 3D prints. These unwanted plastic strands appear when the print head travels from one location to another without depositing material. To determine if your 3D printer is prone to stringing, use this quick and simple test model. Adjust your slicer's retraction settings accordingly to minimize or eliminate stringing entirely.
