TwistWire Nozzle Brush

TwistWire Nozzle Brush

I designed the TwistWire Nozzle Brush after receiving something similar in the toolbox that came with my Snapmaker U1.

It uses a stainless steel wire bore brush with a 1/4" hex shank that friction fits directly into the printed handle. The cylindrical shape makes it really easy to work around the nozzle from any direction. You can scrub back and forth, side to side, or rotate the brush as you go if plastic starts building up in one section.

The twisted wire construction also leaves some natural spacing between the bristles, which gives loosened plastic somewhere to go instead of immediately packing the whole brush. Since the bore brush itself is replaceable, you can also keep using the same printed handle whenever the brush eventually wears out.

Wire Bore Brush

This is the wire bore brush set I used:

You do not have to use this exact brush. The handle should work with other steel wire bore brushes that use a standard 1/4" hex shank, so you can go with a longer or shorter brush, a different diameter, or a different wire thickness depending on what you prefer.

For reference, the brush I designed around has:

• 17 mm brush diameter

• Approximately 45 mm long wire section

• 1/4" hex shank

• Stainless steel bristles

If you are sourcing your own brush, I would use those dimensions as a starting point.

Textured Handles

The textures on the patterned versions were created using CNC Kitchen's Bump Mesh tool:

Bump Mesh makes it really easy to apply patterns directly to an existing model.

I also included the smooth version so you can customize it yourself. You can run the smooth handle through Bump Mesh and apply your own pattern, or simply enable fuzzy skin in your slicer if you want some additional grip without modifying the model.

Provided 3MF Files

I have included prepared .3mf files for:

• OrcaSlicer

• Snapmaker Orca

• BambuStudio

The patterned handles have carefully painted seams positioned within the texture so the seam is essentially hidden once printed.

I also added height range modifiers to the prepared profiles to make the handles as efficient and easy to print as possible while still keeping the areas that need detail looking clean.

You can of course use the raw models and slice everything yourself if you prefer.
