BCN3D Sigma R17/R19 brush-wiper replacement

I have had poor success with the stock wiper pads on the BCN3D Sigma. Material would frequently fail to shear off during a wipe and would become embedded in the part. Brush wipers fixed that problem for me. The brushes are the cheap brass/plastic handle variety off of Amazon, link below, with the handles chopped off. I also had to pull out the first three bundles of wire in order to make them fit ahead of the nozzle. https://www.amazon.com/gp/product/B0819D7H66
