I'm wondering whether anyone has had a go at making their own fiberglass volumes? I wouldn't mind knocking out a few for a prospective home wall because the real things are eye-wateringly expensive. However, I can't seem to find much online, apart from this video: https://youtu.be/_X2lYLXBMGc
Which is ok as far as it goes, but seems to leave no options for >1 volume for each design.
