I'm one of those parents who wants to send kids to school with a CO2 monitor, but school hadn't allowed it yet. I'm looking for a protective case that the monitor can stay in while measuring, like the homemade 3d printed case that was in the US newspaper coverage of these devices. Ideally it would attach to backpack or lunchbox handle so kids could have it with them in the classroom.

This is a sturdy case that is the same size as the Aranet4 box, except that the corners are round. I haven't done it yet, but the foam that's in the box can be trimmed at the corners to fit the case and immobilize the Aranet4 in the case.

Could someone @aranet-techsupport update the link to 3-D printing protective case information? Visiting it now redirects to aranet.com homepage. Thank you.

Hello, I am not sure if the problem is on my end or if there is a problem with the model in the STL file. I had the parts printed for me at a library and while the main housing seems to be a proper fit, the front cover doesn't appear to be correct. If I align the top cover with the top side of the main housing, the screw holes at the top are lined up, as is the square cut-out/window for the Aranet4's display.

However, the length of the top cover is too short and the bottom screw holes don't line up. The nut wedges are also inappropriately sized (too long - not the same as too wide, i.e. I don't need to lightly file the sides). Lastly, while the M4 screws I have thread nicely into the main housing, they appear slightly too large in diameter for the top cover as printed.

Is it a matter of the top cover being scaled incorrectly during printing, and I need it to be printed a little bit longer, yet shorter for the cover and the wedges to fit? What should the actual dimensions be in mm for the cover and/or nut wedges?

Thank you.

(The CO2 reading is very high because I was basically breathing directly on the unit while trying to take a photo in my office at home.)

Hello,

It has been noticed that a similar scaling difference appears when printing both details at once. Our advice is to print the details one by one. And keep in mind configuring "global" shrinkage compensation of +0.6% for PLA and ABS materials.
