So! I have mixed reviews over using these models for the past year or so. They're great overall! But... they tend to have some hiccups.
Canines: You'll need to go in and "Solidify" them by .25mm because the walls are so thin in some spots that it leaves gaps in the filament.
Also? The skulldog set? The top jaw parts are completely hollow and need to be modified to be solid. Will absolutely fail on your printer and make spaghetti nonsense. Took me ages to diagnose what was going on until I realized it was only printing one wall and using zero infill.
Straight out of the box? 2/5 stars
Once they're modified and fixed? 5/5 starts.
Super popular on my shop and consistently getting orders.
Looking forward to getting more bases from this shop!

I'm sorry you're having issues with your printers or print settings, but I've successfully printed every headbase I sell with no issue (the sample photos are at-scale, successful prints.)
Every base will print successfully with a raft or large brim (depending on your bed surface), and the only base that will require support is the skulldog.
