4" Wide cleaning attachment for Dyson vacuum. I'm not sure if or how the attachment method changed between vacuums but it fits V6 for sure.

Designed with 1.6mm wide walls so should be good with (4) .4mm wide passes to minimize infill.

No supports needed but will get a little overhang dribble at mount that doesn't affect attaching but it's easily removed if it interferes with OCD. Also, definitely use a brim when printing...
