If I use the 221 Robotics 17t double #25 sprockets it would help some, but the belts would still be much easier to assemble.

A little tip for using spacers with sprockets in a tube if you encounter this in the future would be to use a few small drops of super glue to connect the spacers to the sprockets. Why struggle with a bunch of small pieces when you can connect them together and have one assembly to drop down into the tube?
The bond is strong enough to get it assembled and if you want to take it apart later they aren't hard to break apart.
Using this trick made assembling chain in tube so much easier last year.
