Layers squish at 40%
Having trouble printing this rod. At about 40% complete the nozzles is too low into the model. Not sure hwy it won't let me upload the 3mf file. 
RE: Layers squish at 40%
zip compress the .3mf file, then attach the zip file to your next post.
I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility.Location Halifax UK

seems to be a bit better if i decrease flow and speed to about 40% but I don't understand why.

I think it gets to0 wobbly when it gets high, it will leave extra filament the higher it gets.
You need to find another way to print this, maybe with support in some way.

And wouldn't it be better to print this horizontally? Trying to print such a 5 x 260 mm rod vertically is nonsense, it will start to spring in the higher layers and that's the cause of all the problems! And maybe it would be even better to buy such a round rod ready-made from a local retailer or on Amazon.

I couldn't agree more. Besides the challenges of printing it vertically, the result will be very fragile compared to a stock rod or tube. Just buy it off the shelf -- 4 mm diameter rods are available in various materials, and they will all work better than 3D-printed PLA. Not sure where you are based; in Germany 5 pieces of 4 mm PVC rods, each 500 mm long, cost 3.42€ at Pollin.

The layer time is short so the layer below has not fully cooled before the next layer is being extruded. This basically causes it to shrink inward. Usually from long thin rods like this you either print them at an angle or horizontally if possible. Another way to fix this if you have to print vertically is to print 2 or more rods at the same time separated by a few centimeters. This will slow down the layer times. Also in preview you can see what the layer times are and in filament settings increase cooling and slow down when the layer time is equal to that number.
Or, as @Jürgen correctly pointed out, buy them pre-made.
