Ender 3 V3 SE/KE Automatic Brush Nozzle Cleaner

This is a fully automatic 3d printed brush holder that can clean your nozzle before every print using custom gcode. I remixed my model from this model: "https://www.printables.com/model/742343-ender-3-v3-ke-and-se-automatic-nozzle-cleaning-bru". Ive changed the original model from my model by adding one extra arm to grab on to the plate. I did this because the original model was wobbly therefore having less nozzle cleaning abilities. Also, to attach the Bambu Labs brush I had in the pictures, I used this model: "https://www.printables.com/model/969575-blobifier-dropin-adapter-for-bambu-silicone-nozzle".

Here is the custom gcode I used for the automatic cleaning before every print. You might need to tweak these codes, every printer is different.
