Note to printables staff : this is NOT a remix of a different model that doesn’t allow remixes, it is an original design of my own making where I invested significant effort. As proof, I am including the Fusion360 CAD files here to prove my design is original from scratch and not a “remix” of that model. It is only a remix of my OWN model. I do respect licenses of others.

Note to everyone else: Now includes Fusion360 Model (because reasons.. ) !

Some people suggested that they would prefer to use a toothbrush or brass bristle brush to clean their threads instead of the parent Super Screw Scrubber design with paper towel.

For them, I've designed this alternative version of the scrubber that lets you slap on a cut-off toothbrush or brass bristle brush or similar and glue it onto the guide. This simple but effective modification lets you get a deeper clean with a longer reach!

This version is the more reliable tapered version from the parent that should reduce any first layer print issues. Since the brush bristles are the key to cleaning in this version, the exact tightness of the threads is less important.

Versions

• DefaultSize (Recommended)
• ShortBrush - if you have a brush that's not quite long enough to comfortably reach, this offers a closer spacing of the flat part to the lead screw by ~ 4 mm.

Print Instructions (same as parent)

• Print at high layer resolution, I recommend 0.1 or 0.08 if possible on your printer, so that the threads fit nicely. There are slight tolerances built into the thread design so that it should clamp nicely.
• Most filaments should be fine.. but I would avoid anything like carbon fiber or glow in the dark filament to avoid any scratching of the screws (though most are made of steel that probably would not scratch anyways).
• Orient the flat side down. I designed the part slightly asymmetrically so this is intentionally hard to screw up when placing on your bed :).

Use instructions

• Find an old toothbrush or brass bristle brush, cut off the head. Use hot glue (recommended) or some other suitable glue to attach the head to the flat section as shown in the pictures.
• Attach the clamp and brush to your lead screws as shown.. run the bed up and down (make the screws rotate), and hold the clamp in place as you do so.
• Remove the widget, and clean the gunk off (can just rinse with IPA and/or acetone for most greases).
• Re-grease your threads if you stripped all the grease off.

• Don't use as a regular toothbrush anymore, the ADA has informed me this is not an approved dental product after this modification :).
