- 3 x springs from 3 other Gardena quick connectors
- 2 x plastic pen tips
- 2 x pins
- 1 x bottle cap
- length of wire
- length of T8 FTC tubing (70mm & 35mm) (or similar size tube)
Example: (https://www.1000bulbs.com/product/242/PLAS-100269.html )
- Electrical tape
- Epoxy glue

Tools
- Drill and 5mm drill bit (drill bit needs to match tubing OD)
- Sandpaper
- Scissors
- Craft knife
- Pliers

Make sure that the Gardena quick connector you are using will not slide into the FTC. There is a flange on the quick connector just behind the thread. The flange diameter should be bigger than the FTC diameter. Some cheaper brand quick connectors are slightly narrower and could potentially slip inside the FTC.
