Introduction: Adapter for Ryobi 18V Batteries
Use this 3D printed adapter to power all of your things with a Ryobi 18V battery.
I used this to power a TS-100 soldering iron, but it can be used with just about anything that can use the Ryobi batteries voltage.
Step 1: What You Will Need
You will need:
- 3D printed case. Files at: Thingiverse
- Ryobi One+ battery
- 2 spring contacts
- 2 screws for securing the spring contacts
- 2 ring connectors for attaching to the spring contacts
- Wire or cable to connect to your device
I put a few electrical kits together if you want to buy all the small pieces in 1 package: Electircal components
I also have a kit with the 3D print included too incase you can't 3D print your own: Case and Electrical Components
Step 2: Terminate Cable to Ring Connectors
Drill a hole through the case. In order to keep the hole small I routed my wires through before adding the ring terminals to the end.
Step 3: Stack Up the Components and Then Screw Them Down
Put all the electrical components together and then screw them down. The ryobi battery should have +/- marks on the top that you should be able to use to help determine positive and negative.
The stack up goes: Screw - Ring Terminal - Spring Contact - Case
Using some tweezers may help make the installation easier since you are working down inside the case.
