Hi, Smitty anwering your PM, I can tell that when I start to build my UFS, using the Ody drip base, the rebuildable part and the mouthpiece from my Ody V2, I realized that I can't close the UFS because the refilling cap from the UFS was touching the mouthpiece even with the UFS liquid control close and that thing don't let fix all the parts, so I use three thicker orings between the all the pieces (UFS base, the upper body, the glass window and the refilling cap) then these orings give me the sufficient space to use the Ody drip so that is the way I use my UFS, as Imeo said I use the upper body connected to the UFS base in a wrong way but is what I liked because I like to see how open is the mouthpiece, when I'm using the juice control of the Ody not the one from the UFS and I like to see the level of the juice, so I don't know if this answer your question, if not let me know and I will try extend more my message.
In the next post you could see what I'm talking:

Imeo, sorry if this post is in the wrong thread, if you want to change it for me it's ok.
