So mostly finished the design for my prototype DNA 250c squonk mod. There are a few things that need to be worked out on the final prints still, but for now I believe that I have a working prototype. I am going to assemble it this afternoon. I ordered a MM 510 v6 and it has the same neck that you showed me with the threads that will work on the SXK neck. The delrin washer finally broke on me with it so that device is out of commission until the new 510 gets here in the mail. I've looked everywhere to try, and find some type of elbow adapter like the one that SXK made for their boxer style mod. However there is nobody who even carries anything remotely similar. So I guess for now as you can see it will have to be pulled back the way the VTC device is stock. I did manage to make an insert tray with its own dedicated drain on it so that it can push the squonk bottle up against the back and separate it from the chipset.
