Parametric Ring Alarm Outdoor Contact Sensor Template and Offset Mount

Motivation

I needed to close the gap on the Ring Outdoor Contact Sensor mounted to my gate so that it could reliably detect the magnet.

Solution

Model the main parts of the sensor and magnet and design a customizable offset mount.

Updates

• v2.0
  • Fixed the support arm to be thicker resulting in better durability
    • The picture is still of v1.0, but the differences are apparent in the 3D Viewer

Customization

So far, I've only created the offset magnet mount that I needed for my purposes, but you can customize the parameters (DESIGN | SOLID | MODIFY | Change Parameters) to your gate/sensor or hardware dimensions. The included model is for an offset of 15 mm in X (lateral/toward the sensor) and 13.3 mm in Z (longitudinal/parallel to the sensor). The screw spacing matches the magnet in case you realize you need this mounting adapter and would like to use the same holes after you already tried to mount the magnet directly.

Let me know (Messenger | Printables.com) if you need something else modeled and I'll consider helping.

Printing

I printed the offset mount with PETG oriented as shown in the 3D Viewer. This orientation requires supports. You can also rotate it vertically 90° so that it rests on the wide part on the face of the magnet’s mount that faces the sensor. But, that will orient the layers around the mount’s screw holes in a way they could easily separate depending on how tight you screw it into your gate.

I also chose to print with a brim, but you may not need it.

Assembly

I used the following parts to assemble the included model.

• (2) M3x10 bolts (socket head)
• (2) M3 nuts
