BCN3D Sigma R17/R19 brush-wiper replacement

I've experienced subpar results using the stock wiper pads on my BCN3D Sigma. Frequently, material would resist being sheared off during a wipe and become stuck to the part. Brush wipers resolved this issue for me. The brushes I used are the low-cost brass/plastic handle type available on Amazon, with their handles removed. To fit ahead of the nozzle, I also had to pull out the first three bundles of wire. https://www.amazon.com/dp/B0819D7H66
