Kidde Smoke Detector Mounting Adapter, remix

thingiverse

While replacing my 10 year old Kiddie wired Smoke Detectors, I noticed that the new detectors were not compatible with the old mounts, and I could just relocate the detectors, but then I would have to patch and deal with the AC connection in junction box. I found https://www.thingiverse.com/thing:1416038, but it looks like my inner ring fit exactly within the 1.5" hole in my old mount, so I needed to remove a little bit of the upper shape to fit. After simply reducing the size of the upper cylindar, the edge of the inner piece was to large to fit inside the junction box, so I trimmed off a little from the edges, as well as some unneeded materials from the base.
