OpenSprinkler 3.3 enclosure

[galmiklos]

Hi,

I started building the latest OS (3.3) from github (https://github.com/OpenSprinkler/OpenSprinkler-Hardware), but I couldn’t find any enclosure 3D models there. I found a link in one of the other posts (https://opensprinkler.com/forums/topic/instructions-for-testing-os-3-2-with-w5500-ethernet-module/), but it doesn’t seem to exist anymore. The only model I found was on thingiverse, but it’s for version 3.2.

Could the official 3D models be uploaded to github, please? Or is that model on thingiverse the official one? I printed it, and it looks like the 3.3 boards fit. Perhaps there is no need for a specific enclosure for 3.3?

Thanks,
Miki.

All version of OpenSprinkler v3 (including 3.0, 3.1, 3.2, 3.3) use the same enclosure.

Thank you for confirming, Ray!

Any chance the enclosure design files could also be shared on github? The ones I found on thingiverse.com don’t look like it.

Thanks again,
Miki.

The official OpenSprinkler v3 enclosure is designed and owned by SeeedStudio. I will see if it can be posted, but it’s a design meant for injection molding so the enclosure thickness may not be suitable for 3D printing, and it has many small structures which are definitely too small and thin for 3D printing.

Thank you so much for trying, Ray! 🙂 I was thinking about printing it with a resin printer. Some of the resins are designed for prototype modelling, you can even tap holes with the one I use (https://siraya.tech/products/build-resin-drillable-precision-printing).

Hi @Ray, Have you by chance got the design files from SeedStudio? I don’t see anything new in the github repo.

Thanks,
Miki.

Any luck getting the STL for the W5500? The case shipped to me is definitely FDM printed, not injected printed as I can see the layer lines and the bottom layer pattern. I would like to extend the design to mount to a DIN Rail. Thanks!

This post was about the OpenSprinkler main controller enclosure. You are referring to the wired Ethernet (W5500) enclosure, which is 3D printed, as the product page says explicitly. The OpenSprinkler main controller enclosure is injected molded.

I was look for the mounting hole positions for the OpenSprinkler 3.3 enclosure?

I know from the FAQ the OpenSprinkler 3.3 case is 140×56×33 mm, and from the photo has four mounting holes, but I can’t find the distance between the four mounting holes? I thought about looking at the printable case but not sure if it is identical to injection moulded one?

The injection molded enclosure files for OS v3.3 are publicly available here:
https://github.com/OpenSprinkler/OpenSprinkler-Hardware/tree/master/OS/3.0-3.3/Enclosure
This is the exact injection molded enclosure file, so yes the mounting holes are accurate.
