Ender 3 V3 KE & SE x-axis nozzle brush - No support!

The other models required support and I thought I could do it better, so here is my version. I was inspired by AlehandoroVR's model , however my design and files are completely original.

Other then the brush , no additional hardware is required. The fit for the brush is VERY tight and you will likely have to use the edge of a table to push it in.

It clips onto the metal part under the bed like so. Please wait for the bed to be cool before installing, otherwise you may burn yourself

You will need to modify your start gcode. Here is mine to get you started, but you will almost certainly need to adjust the positions to match your setup.
