Silicone brush mould

I saw on youtube that using a brass brush will damage the nozzle for my Voron 3D printer. So I designed and made a mould to make a silicone brush to clean the nozzle and surprisingly worked extremely well (a lot better than I expected). 

The size and shaope of the silicone brush was designed to fit the brush holder and purge bucket in my other design.

This is will require 4 x M3x 20mm screws with 4 M3 nut bolt on the other side to hold and tighten it. I recommend using 0.4mm with at least 20% infill, material is not important as I used PLA and it worked fine.
