Bottle brush, with long handle

Quick re-hash of a good bottle brush design.  This remix now allows for cleaning of larger diameter (~40-60mm dia) and much longer vases (from IKEA for example).

Great basic design from LoboCNC - remixed as follows:-

• Scaled up the brush diameter by 25%.
• Added a much longer removeable handle with threads to enable later brush replacement.
• Reduced handle diameter to become slender, and slightly flexible when used as a bottle brush.

v3 update:-

The Extended Handle now incorporates M8 threads; so no need for a separate M8 Stud item.  A Boss with grip features added to the Brush to aid fitment of the handle.  The previous version .stl files (see .zip archive) with Stud are all still compatible.

Printing:-

The Extended Handle prints lying down on the build plate (min print bed size is 220 x 220).  Printer settings are required really dialled-in for the threads and overhangs, or it's also possible to just post-process using an M8 tap to clean-up the handle threads.

I advise adding a modifier down the centre area of brush, where the bristles attach to the body, with slightly increased flow or line-width.

Filament:-

• Handle & cutter tool are from Yellow eSun PLA+
• Brush is from White Fiberlogy Easy PETG

Post-Process:-

On a steady and firm surface, push the cutting tool straight-down to shear the bristles from their printed sheath.  See the original make from LoboCNC for details.
