There was nothing technically wrong at all with the model or instructions. the issue I suggested was a mechanical one. As I print my models on expensive cardstock, the current model/instruction layout would force me to print all 102 pages on cardstock, and all the instructions print would end up in the waste pile. I had suggested that a separate "parts only" pdf be created, that would probably be in the order of <50 pages, thus making my waste pile much smaller. I'm perfectly happy with the 102 page instruction booklet, as I rarely print the instructions, but for the sake of those that do print the instructions, it was natural to also point out that a "instructions only" pdf that the user could print on cheap paper and not cardstock might also be environmentally thoughtful.
