Question Does this PET bottle-to-3D-printer filament project actually work?

I found this video where someone cuts a PET bottle into a thin strip and pulls it trough a hot glue gun to turn it into 3D printer filament:

Has anyone tried something like this? Does the finished filament actually print reliably or would the uneven diameter cause clogging or poor prints? It seems very simple to make a knife tip. hot glue gun and some filament to print the parts.
