Since the summer will be hot and not much rain and I'm a lazy person I made a simple watering system. I had some 20mm PVC piping left since I built my hoop house so I remixed a gardena fitting, made a plug and also a tool to make straight lines on the pipe!

Since PVC pipe is easy to get anc cheap you can make lots of watering systems with this method. Buy some 90º angles and make it into a square for your raised beds. Bend it to a circle around your trees or bushes. There's no end to the possibilities!

I printed it with 100% infill but I think that 80 or even lower might work. Use cooling fan and you won't need supports!
Step 1
Lock your length of 20mm PVC in place somehow, then use the tool and a pen to make a straight line on the pipe. Take a measuring tape and make a mark each 100mm for example

Step 2
Drill holes on each mark, I used a 1,5mm drill but I think you can use a tad larger one to. It depends on your water pressure and the number of holes.
Step 3
Fasten the coupler and the plug on each end using silicone, glue gun, epoxy or anything else you have available.
Step 4
Connect the water hose and let it flow. Great, now you can have a beer/wine/coke instead of carrying water all day!
