This is an ultra-simple handle to use the adhesive-mounted silicone rubber brush pads (pads originally made for Bambu A1, and available for as little as US$3/dozen). Has a bent handle so you can get the brush down under your nozzle without blocking your view. Prints really fast and easily without supports. The tip is angled downward to minimize risk of damaging anything that sits behind the nozzle (such as a Beacon/Cartographer sensor).
If you are newly getting into 3D model designing, something like this would actually be a good concept to start with – design your own rather than use mine. But if you just want a brush to safely clean your nozzles with least effort, here it is, a quick print you can make with nearly any filament.
The author marked this model as their own original creation.
