TPU print stringing

I'm using "Ooznest TPU Bend", it's ok if you print only one object on the bed.
If you run it at 15mm/s it does not jump out the side - in fact it will run faster than that - but don't be greedy.
I use their suggested profile. I do not use retract. Z hop is on. I have an enclosure, but I leave the door open - it does not seem to matter. The bed is 50-60ºC and the nozzle 240ºC.
Stringing is a real pain. So this means that if you print multiple objects or objects with large voids - you will have a hell of a clean up job.

Vase mode prints perfectly as the head never lifts off.

Also support material is hard to remove - but often pulls off without scarring,  despite having to man handle it.
Sometimes it is a real pain to remove.

I often print pods for quads/racing drones and I smooth them with a heat gun which can look sweet - but it's really easy to overdo.

This pod is printing atm - it's really hard to photograph but the texture is lovely.
The only issue is the stringing ( and the globby stuff on this print due to the head having to travel through a no printing part ).

I'd love to get rid of the stringing. ( This looks 5x better in real life - the texture is sweet ).

Here is a before and after pic of the stringing - the after pic is not as good - it looks really good in real life. It only needs to be functional.

In the file section in the Prusa Community on facebook there is a tpu file I have used called pp something and there was no stringing on pieces I made.

RE: TPU print stringing

Dry your TPU. Stringing gets worse as it absorbs more moisture.
