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?

It's very interesting to scroll through and I could easily find my way in it. It is also very fast. Thank you for sharing.
I have the tendency to lock everything in place and fixate it based on some logic. For example: I would constrain Sketch010 for PocketGlandHoles so each of the holes is exactly the same distance. Lack of experience makes me want to have a parametric model so I can move things around until I make up my mind. Looking at this file however, it may be better to just model again when things change.
I'd love to have another peek if you screw up with this approach or if you'd have a finalized version.
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).
