I had some problems with my bowden tube that is slightly less wide than the original so i printed the Bowden tube tightener it's a lot better now
Thakns for the nice post

I always had doubts with the bowden tube tightner but they are based on theory and not my own experience. I always think that by clamping the bowden tube the ID can get even smaller or deformed which can create more friction i.e. under extrusion. Also, if you move to the front end of the build plate, or even the front right (as far away from the feeder as possible) the bowden tube has to stretch to its max and due to its size / height you can get a kink (is that a good word?)
How does it work from your experience?
Did you experience any of these things?

You're right, you do end up reducing the inner diameter of the tubing at its most distant points from the rear left where the feeder is. So far my tube is still new and fresh so any resistance is somewhat negated by the still slippery inner surface, I'm sure over time the feeder mechanism will have to work harder though.
Eventually I'll be enclosing this case to try and help filter ABS fumes during prints, so part of that modification will be to move the feeder system to the top rear center of the machine to reduce some of that tube stretching and avoid kinking against the new top cover. Even without the enclosure I'd still most likely end up working at the relocation of the feeder.

For other people: if your fans are hitting the side of the printer it's usually because they are bent wrong - this is common - or because the limit switch is off by a millimeter or so. But printing a smaller fan shroud works also and some of these alternate fan shrouds have better, more symmetrical cooling.
