I had 3 failed prints where the teeth either shifted or got bumped during printing and caused the entire row to spaghettify or rip off the plate. To fix this I added a new profile where the model is split in half and layed on its side requiring no supports and making the print easier.
My only other issue is that some mini-spools will not work if the gap between the sides isn't wide enough so I will still have to rely on other adapters for those spools and those that do shift around a lot.
Printed V3.0 in blue translucent PETG but broke trying to remove from build plate. Then printed the split version in ABS.
That works so much better and the one I would suggest. Strength is way better and has more slots for different size spools. Weight supported nicely on center console between spools. Well done
