Smoke Detector Adapter

Adapts a smoke detector with mounting holes spaced at 60 mm to preexisting mounting screws spaced at 90 mm.

I decided it was time to replace the antique smoke detectors in my house. I think the old ones must have used vacuum tubes because they were so big commpared to the new ones!

I could have spent 10 minutes removing one of the screws and poking a new hole in the right position. But why do that when I have a perfectly good 3D printer just sitting there and hours of a cold February Sunday just begging to be wasted?!

So here we are -- a 90mm to 60mm Smoke Detector Adapter Plate.
Enjoy!
