Carriage can be slide on/off from one side. Print the carriage holder with the length parallel to your z axis and a small brim (~2 mm) for adhesion, if needed.
So long as you don't have too much blobbing before and after extrusions on each layer, it should not affect sliding these on too much. If anything, the fitment might be a bit too loose, so use with some caution. O
Useful for sliding the carriages back onto the rails without the ball bearings shooting everywhere.
Don't have any pictures this time as I finished this project quite some time ago. ;(
