Thanks a lot guys!
It is Voyager's. It isn't far to easy. The biggest problem is get the correct alignment.
I made chanels in a plastic plate with the distances indicated at instructions and put the plates in that. Then I started to cut the thin tubes in the correct size and introduced each one in the plates, using super glue.
I do not know if my english was enought to make myself understandable.
Jason, it is a great set. If you didn't understand, please ask again. Then I will call my son because he is english teatcher.
Cheers!
Marco
