Hot off the press....
So I set out to make a "Double Barrel" fan adapter for my FauxMado grill because I wasn't getting quite enough air flow for high heat pizza cooks.... one thing leads to another and the next thing you know I have a new servo damper in hand! I am FINALLY getting the hang of using 123D to create 3D objects, it can still be frustrating at times but I got this valve designed really quick....
I decided to leave the bottom open so I can use it as the damper alone, I stuck with the same diameter as the (outer shell) of the PVC tube I've been using so I can use the adapters for various fans I have made already.
Here is a pic of the damper connected to my FauxMado burn pan with the "Double Barrel" design on the vent:
Here is a pic from the servo side:
Here is a pic from the other side showing the CAT5 connector that connects the servo and fan to the HM. I am going to use snap connectors on the fan so I can use any of the various fans I have laying around. I have also added a CAT5 connector to my Heater Meter so I can now use a standard CAT5 cable to connect the HM to the servo/fan... The CAT5 jack snapped in perfectly on my first draft... SWEET!
EDIT: Here's a pic of my Heater Meter with the CAT5 jack:
Here is a pic from the bottom, you can see one of my fan adapters sitting beside it, and in the background is the "Double Barrel" adapter for my PVC servo damper that started me down this path:
I just got it together, haven't tested it out yet. I know this will be my "go-to" adapter for pizza cooks, the valve is rather large so I'm not sure yet if it will be my best valve for low and slow cooks on my FauxMado or not. All in all I am very happy with how the design and print of this valve went, it's really nice to finally have a better grip on how to get things done in the 3D printing world... Thank you very much to Tom, Matt and Bryan for helping me out a TON along the way....
EDIT: BTW, the reason I went with the "Double Barrel" design is because large pieces of copper are kinda expensive. I've got a stick of 3/4" pipe here and 3/4" fittings are cheap, so double barrel it is. I was afraid to put plastic right into the vent on my FauxMado, it would DEFINITELY melt during pizza cooks. So the copper gives me the few inches I need to make the temps more reasonable...
