BrushBox | Nozzle Cleaner

thingiverse

I built this tool from scratch so I could clean the nozzle before the auto-leveling process. I chose magnets for easy maintenance, and cleaning is a breeze because of it. By attaching the BrushBox to a bed-clamp, you can move it wherever you want, making it easily accessible from the nozzle. You can add G12 P1 S4 T2 ; after home axes in your start G-Code, but first you need to enable this feature in Marlin by commenting out: #define NOZZLE_CLEAN_FEATURE. To assemble everything, you'll need to drill two holes into the bed clamp using a 2mm drill bit. A drill guide is included for this purpose. Here's what you'll need: * Eight 3mmx1mm Neodymium Magnets (https://banggood.com/3mm-x-1mm-N35-Rare-Earth-Neodymium-Super-Strong-Magnets-p-923000.html?rmmds=search&cur_warehouse=CN) - The holes are tight enough that you can push the magnets in without glue. * Two 10mmx3mm Neodymium Magnets (https://www.banggood.com/20pcs-N50-10mm-x-3mm-Strong-Round-Magnets-Rare-Earth-Neodymium-Magnets-p-984372.html?rmmds=search&cur_warehouse=CN) - These magnets need to be glued onto both parts. * One Copper Wire Brush (https://www.aliexpress.com/item/33053117369.html?spm=a2g0s.9042311.0.0.4c184c4d6wFbhd) - You'll need to cut off the grip from the brush. The inner dimensions of the main body are 38.5mm x 13mm, so you can use another brush if needed. If the brush doesn't fit, sand down the cut part until it does. * Two M2 Hex Nuts * Two DIN7985 M2 - L5mm
