I'm trying to install this into my Ultimaker 2. What I am not understanding is how this fits into the cut out in the rear panel

Assembly instructions are in the comments. Repasted below:

Insert the bearing into the male wheel, and thread the female wheel onto the other side. Take the bolt, assemble the washer, the bearing assembly, and the bracket. Insert the plug into the recess in the bottom of the bracket (refer to the exploded view for correct orientation). Thread the mounting nut loosely onto the bolt (just a few threads). Take the assembly and push the mounting nut through the large hole side of the mounting slot on the machine. Slide the assembly over, the base of the bracket should sit flush with the back of the machine and the plug will fill the rest of the mounting slot. You should then be able to tighten the bolt to complete the install.

Okay that helps some....sure is a lot easier to remove the Y motor cover and secure from inside

To design for? Absolutely. To use this design? Absolutely not. Leave the screw loose, shove it in the large hole, slide to the right and tighten.
Or this one works without the key slot also - http://www.thingiverse.com/thing:1245216

UM2 Bearing Filament Guide V2

The 626 files scaled to 85% adapted very well to the 625 bearings I had laying around. Awesome design, thanks!!

Is it possible to adapt this thing (the wheel at least) for 623 bearings? They have OD=10mm and 4mm in thickness. Or they are too small?

If you want to use just the wheel, yes it can be modified for a 623. To use it with the bracket it will need to be modified to use a 3mm screw also, the original uses a 4mm screw which wont fit in the 623.
If you need the wheel only you could build a spacer use the existing design. There are a few ways to do it but the easiest would probably be If you use the 626 wheel (626 Bearing: 6ID x 19OD x 6THK) your spacer needs to be 10ID x 19OD x 4THK to fit the 623 (623 Bearing: 3ID x 10OD x 4THK), then make 2 washers, 9ID x 19OD X 1Thk for each side to make it wider and hold it in the center.
Let me know if you need a modified version, I can do it but not until atleast next week.

Attention !!! The Case Design of the UM2 had changed. There is no more original Filament Guide in the backplane. This Bearing Guide will not fit anymore.

UM2 Bearing Filament Guide V2

No more Hole for the guide? Got a picture?

I bought my UM 2 in November 2015 - there is no hole for a filament guide.

Hmm, that sucks. I have an idea how to use the screws in the back panel to mount it. I won't have time to work on it until atleast next week though, but I think I can get something to work, stay tuned...

Please come up with something, I recently got mine as well and am unable to use your filament guide

Thanks alot for your explanation.....now i plug it well.
I think yesterday I was too tired...:)
Regards.

Hy, I have print this parts on the good way.
But how to plug it in the UM2 ?
I need to disassemble some parts in the UM2?
Ca you help me with some pictures .
Thanks

I won't have access to the Ultimaker until Monday. Let me try to explain the mounting instructions. It should install directly on the back without disassembling anything on the machine.
Insert the bearing into the male wheel, and thread the female wheel onto the other side. Take the bolt, assemble the washer, the bearing assembly, and the bracket. Insert the plug into the recess in the bottom of the bracket (refer to the exploded view for correct orientation). Thread the mounting nut loosely onto the bolt (just a few threads). Take the assembly and push the mounting nut through the large hole side of the mounting slot on the machine. Slide the assembly over, the base of the bracket should sit flush with the back of the machine and the plug will fill the rest of the mounting slot. You should then be able to tighten the bolt to complete the install.
