A nice idea. I don't think a little friction will be significant but my endcaps do have the tendency to get loose over time and that is not good. This modification would fix this I guess.
Just thinking, this part doesn't have to be a full cylinder. It could be a 'C' profile, so that it can clip on with the machine in place.

I printed and installed them instantly when I saw your design on YM - I really recommend it to everyone
These are the dimensions i use now, i hope that helps someone (at least as a first orientation):
back: 35mm
front: 14mm
right: 19mm
left: 19mm
But... My rods are driven directly, therefore your back spacers may differ.
BTW, I just cross-checked my measures with the ones from @ataraxis and I had the same +/- 0.5mm, so we can assume it is a very good basis.
For the short belts (yes I'm old school), I printed small spacers (1.2mm) to get just a small space between the short belt pulleys and the wood.

I will raise my priority on making these things for my printer as well. Last weekend I was printing and I heard some new sounds coming from the printer and I found out that one of the axis on one side was loose. The object was a little bit effected but while continuing printing I re positioned the Y axis and got the endcap on one side fixed again. The print was saved but I really need to implement this modification to get this solved.

I made some "C" shaped spacers. They seem to work great and you don't have to take much apart to install (I did have to loosen a bearing on one side to squeeze the second spacer in.)
Sorry, I didn't publish them just because I am not using the normal sprockets and didn't want to confuse anyone. They are pretty simple to make.

Ha I did the modification while I had to replace my xy blocks. Ofcause when I measured my distances I made a 3mm error so when I installed the cilinders there was too much room:( Nothing a hobbiest can't fix but I could not print at time since my printer was missing some xy parts... So I drilled some 8mm holes in some rings to fill the gap. Now everything fits nicely.
I upgraded to the mooncactus xy blocks and they do their job well

That's why everybody should have two Ultimakers...

Printed, installed, works perfect (with ataraxis's dimensions, first try). Great, thank you!
