Think the little clips need to be a little thicker or something. I used the support for PLA filament for the interfaces too and they still snapped off like little twigs. Only giving this a 4 star because I guess I don't really need it to clip in. I would've been a little stronger though.
*Update*
The last one snapped off while being put on... So I'm saying this print was kind of a bust and a waste of time for me. Maybe I'll update my rating after I remix it.
