Hi, I have printed a small holder for a Bowden tube to print from my filament dryer outside of the enclosure, but the filament coming out of the tube is tensioned and I don’t know if it will cause problems later. Is this fine to keep or how can I fix this? This i a Ender 3 V3 SE btw.

What type of a spool holder you have in the dryer? It might be a good idea to get some bearings in there to help the spool spin as freely as possible.
Recommend this. Have a similar setup and you can 3d print spools and order bearings for them. That being said my direct drive filament feeder on my prusa is quite strong. As long as you make smooth curves with your bowden tube it should be ok.
That should be fine, I’ve printed tens of kilograms pulling the filament around a sharp corner. As long as it’s dry, pla can handle quite a bit of abuse. And it’s unlikely to damage your printer or dryer.
In the worse case you might have some dust buildup, keep it clean
It might. Depending on how much tension there is. Too much and it will cause the filament to slip in the extruder causing under extrusion. If you are not seeing signs of under extrusion then you are fine for now - but that might change if you change filament or anything else. I would try to lower how much tension the filament is under to avoid problems in the future. Otherwise it would be something to keep in mind if you do start seeing signs of under extrusion.
But how do I lower the tension? I think its just the friction in the tube.
It could be a tight bend in the line somewhere - make sure there are no tight bends. Otherwise if it is the tube then get a thicker tube.
