I acquired several very inexpensive water flossers, even the parts themselves are worth more than the selling price. However, if I intend to utilize them, I still need to purchase nozzles. The cost of a single nozzle could buy several water flossers. Therefore, I designed this water flosser nozzle and decided to share it. Individuals with the same need can potentially save a considerable amount of money. After all, this device is quite a niche product, not worth discarding if unused but not worth the expense if used. Now you can 3D print a few nozzles, the cost should be merely a few cents. It is suitable for temporary use, or for flushing various items, such as cleaning a computer case or glasses?

I employed transparent PETG for printing, and the effect appears to be more favorable. The layer height is 0.08, and in actual tests, there is no leakage; however, leakage may occur at a 0.2 layer height.

I printed several for testing purposes, and there were no issues. The usage is practically identical to the original, the water column exhibits slight bifurcation, and trimming it with a knife would enhance the outcome.

Printing precautions:

Utilize random or nearest for the seam position, do not utilize the default alignment, as alignment will leave a gap, leading to leakage.
The layer height should be as low as possible, tests have shown that 0.08 and 0.1 are both acceptable, 0.2 depends on the material, some will leak.
A higher fill percentage is preferable, to minimize gaps.
Employ concentric for the top pattern, the default setting will cause the nozzle to deform.

搞到几个很便宜的冲牙器，即是拆件都比售价多，但是如果想利用下，还需要买喷头，喷头的价格可以买好几个冲牙器，所以设计了这个冲牙器喷头，发出来，同样需要的人可以省下不少钱吧，毕竟这东西鸡肋的很，不用吧扔了可惜，用吧不值得现在你可以3D打印几个喷头，成本应该几毛钱，临时顶顶还是可以的，或者用来冲一些东西用，比如清洗机箱？清洗眼镜？

我使用透明PETG打印，感觉效果比较好些，层高0.08,实际测试不会有漏水，但是如果0.2层高可能会漏。

打印了几个测试，都没有问题，使用上和原来的基本差不多，水柱略有分叉，需要用刀修一下更好些。

打印注意事项：

接缝位置使用随机或者最近，不要使用默认的对齐，对齐会留有缝隙，会漏水。
层高尽量低一些，测试0.08,0.1都可以，0.2分材料，有的会漏。
填充越高越好，减少缝隙。
顶面图案使用同心，默认会导致喷口变形。
