Dr G's Protovapor is very sexy... You should give it a try, I've been exchanging correspondence with him here at ECF, and he definitely knows his stuff...
Here's mine
Considering doing a limited run, but the case itself takes about 8 hours to print... I could panelize it and maybe do three at a time... For now, it's my R&D curiosity, the buttons are all from Madvape's... They are cheap and fugly so my next one will have much nicer ones... Also, need to streamline the assembly by building a small breakout board for the wiring into the DNA20 for serviceability...
