[DIY] Nozzle Scrub Brush - 3D Print

Needed a simple tool to manually clean my 3D printer's nozzle. Boogers can accumulate during purging, or during multicolor prints with multiple filament changes. And on some projects, before a print I heat up and scrub the nozzle clean before applying no-stick PTFE on it.

So I stole from Amyrillis on Printables the idea of simply using a Bambu Lab A1 silicone wiping pad mounted on a handle.

The handle was designed to present a very low profile around the pad so as to still be able to reach under the nozzle when it is above the P1S poop chute or during a paused print.

The Fusion 360 CAD, STEP and 3MF files are on Github

Happy booger-free printing to all !

______________________________________________

Fusion 360 model:

Print settings, on a P1S

• PLA, 0.08mm layer height, 0.4mm nozzle
• 3 walls, 7 top layers, 7 bottom
• 35% adaptive cubic infill 
• Ironing on Top surfaces, 16% flow
• 44' duration, 8 grams of filament

When done, stick a Bambu Lab A1 silicone wiping pad in the recessed area.

And tada, with that we got a toothbrush for printers:

Ooooh, talking about toothbrushes: could create an attachment head instead that mounts on an electric toothbrush... Oh well, elbow grease will do for now, got other dogs to skin 🤤
