### led_plugging_tool/
A 3D-printable tool that helps with cutting the LED legs to size and attach them to JST ZH-4 connectors the correct way.
Usage:
1. Print the tool on a 3D printer.
2. Put a LED bulb-first into the tool hole. Especially on first use, make sure that it's all the way in.
- The LED should only fit in one orientation.
3. Use a pair of wire cutters to cut the LED legs as close to the tool's surface as possible.
4. Take a cable fitted with JST ZH-4 connectors and push one connector firmly onto the LED legs inside the tool.
- The connector, too, should only (fully) fit in one orientation.
- You may need to bend the LED legs a little to get them to a pitch close enough to 1.5mm that the connector will slide on.
5. Pull the cable to remove the connector and LED from the tool.
6. Repeat steps 2-5 for every LED you need to prepare.
