Maybe I've missed it somewhere.... Does anyone have the .stl file for an airway transition from Tom's V2 assembly to a 1.5" round tube?
And it's now academic. I had WBegg's transition to 1.25" round tube printed, before I started really working on the smoker mount. I hogged out the round end of the transition with a small rotary flap wheel, then cleaned it up with a 1.5" hole saw (one of the tools I don't have is a drill press, but I can TIG weld aluminum and stainless. Go figure.) I'll post up pics of the mounts in another appropriate thread.
Dang! Wish I'd seen this earlier. Wouldn't have been a huge task to modify my design to fit 1.5" tube. Maybe I'll do it anyway if anyone is interested.
There are two versions for the main part: RSD-BGE-top.stl and RSD-UDS-top.stl. The "UDS" version has the round hole, the "BGE" version has the square hole. You must have printed the UDS version. They should both be in the file. Your best bet is to reprint the BGE version if you need the square hole. Note there are corresponding "cover" files as well RSD-BGE-cover.stl and RSD-UDS-cover.stl. There is only one "valve" file.
I have printed & built the rotary offset damper and can get the servo to work without issue using a 2A power supply with just the servo arm connected to the servo. As soon as I mount the valve part with the fan the servo does not move and makes stuttering sounds. I printed the valve with 50% infill could it be that it is too heavy for the servo to move?
