Baby Gate Swing Stop

This is a replacement gate swing stopper for Summer Infant brand baby gate (example). When installed, it allows the gate to open in only one direction, commonly used for top‑of‑stairs installations. It also makes the gate easier to close because it hits the stop instead of continuing to swing open to the other side.Required parts:2 M3x18mm machine screws2 M3x16mm machine screws4 M3 lock nuts (preferred), or hex nutsRecommended print settings (tested):Auto tree supports10 wall loops10 top and bottom shell layers0.5mm X-Y hole compensation (makes screws and nuts fit more easily)Tested in black PLA with socket head M3 screws and nylon lock nuts.
