Ender 3 Nozzle Cleaning Brush - Remix

Added extra width to get it another few mm to the bed so it can clean more in one swipe. Also added 2.5mm and 3mm holes for more options for locking it down. Will need support if printed in this orientation easily done with paint on with prusaslicer. Check the pics showing mine. 

Works with small zip ties and generic white brass brushes you can find on amazon or aliexpress. Make sure the brass bristles arent so high they can tough your thermister and hotend wires or they can short it. On mine they are only long enough to clean the nozzle.

If you have an ender 3 v1 or pro you will need something to move the screen. Recommend this: https://cults3d.com/en/3d-model/tool/ender-3-screen-extension

Here is the Gcode i added after the purge line in the start code. You can also set marlin up to do with with a G12. Change the numbers based on your printer. This works with MY ender 3.
