These pins are for PTFE tubes that come with a common drip watering system. I needed more pins than are included with the kit, so here they are: printable watering pins. I use this watering system to irrigate the plants on my balkony. I have also created other models like spare rubber plugs for the distribution hubs and garden hose connectors to refill the water reservoir from an automated garden hose. Happy gardening :)
