Parametric micro sprinkler

thingiverse

Here's a customisable mini sprinkler for irrigation systems I designed, but it seems like it could have some wider applications so I'm sharing it with the community. This is a miniature version of a traditional sprinkler that you can customize to fit your specific needs. It lets you adjust the number of nozzles on each one, as well as their size and the distance they spread out across the lawn or garden bed area. You also have control over how big the connector parts are so you can match them up with whatever water pipes and fittings you're working with. The initial settings included in this OpenSCAD file produce the smallest sprinkler design I've been able to get out of my Robo3D R1 printer; anything much smaller starts running into problems with consistent printing quality, causing nozzles to block up over time. I would suggest printing multiple copies at once because if you try to do single ones layer cooling can become an issue, making it hard to produce properly shaped nozzles and potentially wasting more than a little plastic in the process.
