Smoke Detector Holder

thingiverse

I'm installing a bracket to secure my smoke detector above my printer on top of a cupboard. The mounting requires two M3 bolts and tapping the holes to fit perfectly. Although you can make the holes slightly larger, an M3 tap is essential for printing anyway. The smoke detector has a recessed area inside its lip that accommodates screw-heads. The mounting's center point is approximately 61mm, allowing for some flexibility in positioning - up to 1mm either way should work fine.
