Vivint door/window sensor magnet mounting bracket

thingiverse

Mounting bracket for smaller magnetic piece on Vivint door/window sensors fits in snugly if old two-sided tape remains in place. If removed, a folded piece of paper can be slid into the space to secure it tightly. When screwing down the bracket, exercise caution especially when printing with low infill percentages. I damaged mine slightly, but there's no need to overtighten. Larger sensor appears to be attached using two-sided tape as well, indicating that a custom mounting bracket may be necessary once it detaches from the door/window frame.
