Could you put a ruler next to it and post another picture ? Preferably metric if you have access to one 
I'd say it can be printed, and it may be strong enough to be usable depending on the size of it.
I'm interested in giving it a go if you're not especially hurried, I just love the idea of repairing stuff instead of buying a new one and throwing away a nearly working object. Using a 3D printer in the process is a bonus
Edit : ah, www rocks, found some images. Is this the part the wheel is pushed into on image 13 here : [www.ikeafans.com] ?

Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.

Have done a first version, will send you a PM about mailing it back to you.
Pictures - the second one is blurry, sorry, it was moving as it was taken during print, to show the "real tiny holes that actually turns into plastic pillars for internal reinforcement", in the left cylinder. I believe it won't crack at the same place as the original.

Sadly, I have to report that the piece broke yesterday. At the same point the original one did. Photo attached.
It was looking so good... Maybe someone has suggestions how to improve stability?

Rest in peace little piece
Yeah I have a couple of ideas :
1) Try to use that reinforced PLA plastic I bought from Vik Olliver some time ago, it has additives supposed to make it stronger.
2) Try to print the part on its side. The breaking was probably helped by layers separation, so making the layers perpendicular to the forces would certainly help. It will require support for printing then, due to overhangs.
3) I could try to make another one in ABS (like the first blue one was) and dip it quickly into acetone, then let it dry before use. I know people does this to make parts much stronger. It's another way to reinforce layer adhesion, as acetone melt the plastic surface and then evaporate.

Here are the new attempts.
All were printed on their sides (rotated 90° around their longer dimension), so that the layers of deposited plastic are avoiding the part from breaking (it's much more easier to separate the layers than to break across them).
I had to use support to print the parts in that orientation, and it proved difficult with ABS (the grey plastic here) to get the support to stick to the bed, so 2 of the parts (in the background) have warped too much and will probably not be accurate enough. You can see the support remains (horizontal lines) that might have to be sanded for the part to fit.
The center shiny grey one on the picture have been dipped a couple of seconds in acetone, to better fuse the ABS layers together. Hopefully it will add to its strength.
The black one is High Impact PLA from Vik Olliver (diamond age), it's a PLA with additives making it harder. Being PLA it did not warp as much as ABS and was easier to print with support.
Note to people wanting to use that HIPLA : it need slower print speeds, and a fan blowing on the print, as it cool down slower than usual PLAs. It also tend to leave bits of itself in the hotend, which are getting very hard after some time spent heated in there. Get sure to purge your hotend with another classic PLA immediately after your print.
'nuf words, here's the picture :
Hanno, I will post those today or tomorrow.

Well it wouldn't be very complicated regarding design, just cutting off bit 1 and sticking it on the top of 2, and removing the unneeded horizontal remains.

Mmm yeah Bob, 100% infill might help with layer adhesion, but it will also avoid the flexing.
Hanno, I'm not too surprised by the black one cracking open like this, I still have to improve my print settings for that plastic. Let us know how the grey (ABS) one does.
Of course it is worth the hassle ! We learn and we'll finally find a working long term solution

I think I should post an update here.
For two years I used all the pieces DeuxVis sent me and all of them cracked sooner or later. Recently I had used up all of them and contacted him again.
Instead of re-printing the same object we now decided to redesign it. With this new variant the rod of the wheel directly goes into the wardrobe. I think it is unlikely that this variant will ever crack, I don't see how it could.
