SummaryThis is a chuff drip tip for a Troll RDA. I've never been able to find a chuff tip that would fit my troll with the airflow still in place. So when I can't buy, I design. I have two grooves for gaskets but I haven't been using them with mine. Fit's pretty tightly as is. Update 2/18 I uploaded a larger one that should work on other RDA's besides the Troll. I haven't printed it to ensure it fits, so if you do let me know if I need to alter it. Update 2/19 There were a few things I wanted to fix to make it fit more flush on the Troll RDA. Should now be flush with RDA, slip all the way down into the airflow piece, and has a bit deeper gasket grooves. Also I redesign the "screen" to add a vortex and more coverage to prevent hot oil from getting on your tongue.Print SettingsPrinter Brand: 3D SystemsPrinter: CubeProRafts: NoSupports: YesNotes: It's not the easiest thing to print, the lip is very small and its tough to get support underneath there. I did mine in natural nylon with 3D Systems INF support material. I tried to design the inner screen to not need support material, having the entire undersurface curved. When I printed it, there was support in the middle so try it with or without.
