This mini wire tie was part of an experiment to use raw filament in different ways.

After 1 year of using this design, I can now say that it's best to use scrap TPU instead of PLA for the raw filament.

PLA can work, but only in scenarios where the filament is bent into a very gentle radius. The results also depend on the exact PLA used - some formulations become so brittle that no amount of gentle handling will help.
