This bracket mounts to the front right bed leveling bolt on your ender 3 and provides a place to mount the head of a BRASS wire brush for wiping your nozzle before prints, which I find just makes life a little easier because it handles the little bit of filament that leaks out during bed leveling automatically.  

I recommend you follow the setup guide I've included in the download, it will make this installation a lot smoother if you've never done this before.

For this to work you'll need to cut the head off of one of the $1 wire brushes from harbor freight, or here's an amazon link to them: https://a.co/d/eY8qryl

I've uploaded a picture of where to make the cut.  

Also, you will need to make changes to your printer's firmware to enable brush wiping.  I've uploaded the firmware I made for my printer if you'd like to try your luck with that.  It's standard Cr 4.2.2 Ender3 V2 firmware with JyersUI, CRTouch 3x3, and this nozzle wipe.  (Pls note, this code assumes you've mounted the wipe in the front right of your printers bed, if you don't this wont work)

Similarly, you will need to tell your printer when to wipe the nozzle.  This is accomplished by editing the start GCode in your slicer.  I've also uploaded my start GCode for cura.  

This mount only really allows wiping at the start of prints, not between every layer like those mounted on the X axis gantry.  Those mounts require you to grind down parts of your printer, so this is a less involved option.  If you really want to wipe your nozzle in between every layer (for printing petg or other stringy filaments), I recommend you take the extra effort and install one of those mounts. 

If you have any questions feel free to ask.

These fill the gaps in your ender 3's extrusions to prevent debris from filling them up and looking bad over time.

This Config only covers the slots near the bottom of your printer that are likely to fill with plastic bits, If you have a standard ender 3 and would like slots for the vertical portions just let me know and I'll add some.  I've also uploaded the Solidworks file if you'd like to edit it to a custom length.

A very simple container to hold 40 standard M6 Nozzles, they sit slightly loose for easy retrieval in this compact form, but the lid clamps on tight to hold them in place during storage.  

The initial design had them thread into holes but you couldn't fit more than like 15 in this same space because you needed room for the wrench.  If anyone's interested I can post that one too but I hated working with it lol.
