Honda Accessory Plank Plate for Hidden Garage Door Opener

thingiverse

I wanted to build a custom garage door opener switch for my 2005 Honda Element. This hidden switch replaced an unused accessory panel, giving me control over both of my separate garage doors. I took morris1972's design and made some key changes: 1) I eliminated the need for supports by adding a 0.4mm (two-layer) bridge to the "spring" tab. 2) I reduced the thickness of the face to fit flush with my dashboard. 3) I adjusted the switch hole size to match my specific switch. To complete this project, I purchased: * A 3-pole momentary on switch for $0.40 and a matching 3pc wire kit for $0.38 (available at https://www.aliexpress.com/item/4000035585011.html) * A 4-wire cable with male/female plugs for $1.49 (available at https://www.aliexpress.com/item/32966181600.html) The switch is momentary on, so it returns to its center position after being pressed. Here's how I put everything together: 1) I opened my garage door opener and removed the control board. 2) Using a multimeter, I identified which two pins became "shorted" when each button was pressed. 3) I soldered the four pins from the 4-wire cable to the three wires for the switch. Note that one wire will be shared between the two switches. 4) I mounted the three wires onto the switch. 5) Using a soldering iron, I created holes in the garage door opener casing to allow the wires to exit. 6) I pushed the switch into its 3D printed plate and mounted it under my dashboard with velcro.
