As mentioned in a previous post, I have been working with SeeedStudios to design a custom OpenSprinkler enclosure. Thus far I have been using an off-the-shelf Serpac WM-032C clear plastic enclosure, and I have Electronic Precepts to machine the cutouts. It was a good start and really easy to design, but the cost can quickly add up as I order more from them. Over time, it’s make more and more sense to design a custom enclosure using injection molding, in order to reduce the per unit cost.

The initial design has been finalized and a 3D printed prototype is on its way to me. I am very excited because this will be the first injection-molded OpenSprinkler enclosure! It’s a pretty heavy one-time cost (the mold costs about $5,000 to make), but it’s fun and I think it’s worth the investment. I am supposed to receive the prototype today, but a snow prevented DHL from delivering today. So I have to look forward to Monday. But below I attached some pictures Seeed sent me. They are enough to enjoy for a while 🙂 More pictures will come after I receive it on Monday.

    Great news, I’m actually holding up with my order waiting for these to become available (quite an Osborne effect, eh? 🙂 )

    Just wonder if you ever considered an enclosure that would hold both the main and expansion boards. I need 12 zones, I guess I have to buy an expansion; however if expansion won’t have the custom enclosure there’s little sense to wait for it.

    Thank you!

      The expansion board has its own enclosure. I do not plan to put the main board and expansion board in the same enclosure, because some users may want multiple expansion boards.

    Whats the chances of releasing the 3D file for those with hobby printers to give it a crack?

  3. I’ve been exploring for a little bit for any high-quality articles or weblog posts on this
    sort of space . Exploring in Yahoo I finally stumbled upon this site.
    Studying this info So i am satisfied to express
