They SPAM there model in many Variation instead of adding them as STL and Printprofile to there original one.
For me this is a blunt way to get all more attention and points.
The “related” page is full with that!
Probably because the low end points are worth more. It always takes just a few to f it up for everyone else. I looked at those models, it looks like they pop out while printing and break the nozzle, I saw 4 comments with bent hotends. I thought, “That’s nice and misleading” as it looks like an endorsed model that breaks your machine.
One of the featured designers who has posted a lot of stuff ONLY puts renders out there. I don’t think they’ve printed anything before posting a make. Now lots of folks have D/L ed the items, and many printed, so they print.
