I’m designing a case for a dew-point ventilator controller to be 3d printed. The controller is implemented using arduino on an esp32. The project is based off of the code and HW implementation by Make Magazine Germany: https://github.com/MakeMagazinDE/Taupunktluefter. When starting out I was thinking this would be an easy project but it turned out that especially the lid with its lip and groove design and the parts fixations were not that easy. I’m excited to finally print it.

The file is parametric to some extent and the main footprint is based off of a master sketch. Many parts were imported as step files from grabcad. I used FreeCAD 1.0-rc1 which works like a charm for many things. Next thing I would like to do is to use the new assembly workbench. What do you think?

    Heh, that’s also interesting for me to hear. I usually also tend to try and constrain everything and make it as parametric as possible. Since this model became more complex than previous ones I took the liberty to be approximate eg. when lining up the glands and the holes. In the end i just want something printable as quickly as possible. I’ll probably never change the dimensions again. It’s therefore more time efficient to re model things if I ever need to adjust things.

    With the new assembly toolbox I might find an easier way to fit things like the glands and the holes together. Maybe by just tying a cutting object and the gland together and using booleans (which I find quite cumbersome to use).
