Nozzle wiping brush mount

thingiverse

I modified this version to better align with my ender3v2 nozzle. The front of the mount is 2mm thinner, and the brush holder is 7mm higher than the original version. Side walls are removed. Use a m3 nut and bolt to fix your brush in place. Please refer to the original design for the gcode. By the way, I have just found out that the reason molten filament keeps sticking to my nozzle especially when printing PETG with large surface is because my first layer is too low for PETG. I noticed that when set the z-offset correctly which is around 0.04 to 0.08 for mine, the problem was mitigated. However this still happened when the print head moves over the corners where my bed curves up, so I think adding a BLtouch and calibrating the z-offset will be the permanent solution for this. Hope this helpful
