Does anyone have a copy of the .stl files for the Offset rotary valve blower?
After many years of faithful services, i dropped mine and the part the fan mounts to snapped off! Can't seem to access the link from the original post.
I've been using one of these:

Using a rotary offset damper i get about 24 hours at 220 - with 100% fan it lasts about 14.
