Thanks a lot for that enlightening answer! I was feeling pretty much like what you elaborated. Thanks also for the license suggestion, which I will adopt, and for pointing out the difference to the IKEA case. Indeed, the Balton manufacturer do not offer any digital tools beyond a catalogue PDF, neither did they respond to my offer to provide the models.

I expect to see good quality models

Thank you for the flowers. I'm trying my best (couldn't resist[;)]).
