here's some on thing verse .. I think 100 is a bit of a stretch as well . I thought Sweden's were nicer . so just for the record. you don't know what it takes to make an sti file, you don't have a CC . and in your option it takes 10 hrs to make a simple repeating design and 5 hrs to test fit it? sounds like you know nothing.
I think if a creator wants to make a few bucks for his time and sell the file for a reasonable amount that's fine like 10$. if he sells 10 he's made a 100.
I enjoy the pinball community and give back as much as I can . In fact I'll have my draftsmen buddy at work whip up a design in about 30min, I'll make it test fit it and post it here for FREE, unless someone beats me too it .
