Mechanical Dimensions for the Iotawatt

Support
1

My Iotawatt is currently in the mail, and I’m trying to plan an enclosure for it however the manual (and Google) but couldn’t find any kind of mechanical drawings or dimensions of the unit.

Does anyone have the unit’s measurements? This is probably useful information to add to the documentation.

Thanks

Welcome to the community and congrats on the soon to arrive IoTaWatt.

If you do a search for the word “dimensions” here in the forms (magnifying glass icon in the top right), you will find many posts providing you the details being requested here. A few of the posts have not only the dimensions for the device but multiple recommendations of boxes, etc. This data is also available on the Github repository.

Here were my measurements:

IoTaWatt: 27mm x 85mm x 125 mm (1.06" x 3.35" x 4.92")

2 x IoTaWatt stacked, with 1.5" clearance for connections: 2.50" x 6.35" x 6.42"

I 3D printed an enclosure to hold my two IotaWatts. I based mine off this:

Rectangular enclosure with Lid (customisable)

with these edits (so basically change the dimensions to 274mm x 174mm x 127mm and remove the first translate)

Looking to 3D print my own enclosure based on the above design. @cra Do you have a photo of your iotawatts mounted? I only need a single iotawatt, and will be installing 2x power points inside, so want to confirm sizing.

My printer will print up to 220x220x260 apparently, so will need to keep total dimensions under these values. It’ll be outside, guessing you used ABS filament?
