This Nozzle brush is has the head flipped so there is no need for any support or bridging.
I also shortened it to 13.5cm so it fit in the Ender 3 storage drawers.
It's a remix of a remix since most of the work was already done. I Just needed to tweak a few things to get it the way I wanted it.
My print settings
.2mm layer height
20% cubic infill
I used outer wall .4mm and inner .6mm for a bit more rigidity but 2 walls at .4mm is probably fine since the one I printed is solid!
As with the other Nozzle brushes I used sticky felt pads folded in two and wedged together to hold them in place. Cheap and easy to replace.
Heat Noozle, scrub with Noozle Brush 9000, Profit.
