Thanks again for showing this professional application of FreeCAD.
Offtopic: may I ask how the thermoforming itself is done? Is it some kind of a foil which is heated? And if so, how do you avoid stretching the vertical walls too much so that they don't become too thin?
It is PVC plastic, PET what I usually use.
The issue of stretching is something inevitable that depends a lot on height and design to prevent this from being a serious problem. You can also use attachments such as treadmills and pushers so that the pull is not so rough
