Garden Sprinkler

This garden sprinkler has been iterated from one of falcon20cne's Lawn Sprinkler's (https://www.thingiverse.com/thing:414552) remix's done by gruvin (https://www.thingiverse.com/thing:1070626).

3D printer - Zortrax M200 Plus

Flament - ABS 1.75mm

Metal Bar - 4mm

Half Tooth Bolt - 5mm

Drill

Drill Bit - 5mm & 6mm

Needlenose Pliers (if needed)

Flathead Screwdriver (if needed)

Hacksaw (if needed)

Be mindful of the filler situation and the abilities of your machine. I made a carving of a capital D, then printed the body part vertical with the hose connection on the top and the bottom with the indent on the bottom, which caused the machine to build a lot of fillers there, and made it very hard for the fillers to be taken off as you will see. Also, measure your hose and the connection piece correctly, and scale or adjust the model according to yours. I also made a mistake here, as I measured mine and made it the same diameter, but I should have made it smaller so the hose would cover the opening or bigger so the hose would go in it easily.

After printing the model, the fillers must be taken out. This can usually be done by hand; however, the mistake I explained in the previous step the bottom filler was a huge issue to take out, and in general, the fillers were a struggle. The parts that were touching the base of the printer came out okay, however, the back part with the hole to fix the sprinkler to the ground has broken off while we tried to take off the fillers on that part, and the sides with the flat head screwdriver.

Since all the measurements and fillet situations were not ideal, I had to drill them in. I have used a 6mm drill bit for the sprinkler head, and body connection part since the bolt we will be using was 5mm, and I wanted it to spin easily. Also, since we accidentally broke off the fixture part, too, I have drilled it with a 5mm drill bit to still be able to fix it to the ground so the sprinkler wouldn't fly off and wiggle around while on. After drilling, put together the sprinkler head and the body with the bolt but do not screw it too tight to allow the sprinkler head to spin smoothly.

We have cut the bar with a hacksaw since it was very long to be roughly 10cm. One end of the bar was already bent so it would hold the sprinkler in place, but if not, and you will be bending it later on, I would recommend cutting it like 13cm and bending the excess part with a plier.

As I mentioned, I have made an error with the measurements of the hose opening, so ideally, the hose would go in or over the opening with ease, but we had to cut and makeshift the hose to squeeze it in the hole. It still worked, but it could have been better if the measurement were right. After connecting the hose, fix it to the ground with the metal bar, and make sure the bar is not in the way of the sprinkler head. Then let the water flow and sprinkle away! Our garden water pressure is not great, but we first tried it with our bathroom sprinkle head hose, and it had a very wide range, so if you too have good pressure, it would go a lot far from what is in the video. Have fun!
