Brush nozzle servo

My build plate is slightly larger than standard (sourced from a Prusa XL), 

which made it impossible to install a fixed nozzle brush - the print head simply couldn’t reach 

the front or back edges of the bed. 

So I designed a servo-mounted brush that only deploys when needed 😊 

here is example server in action :-)  - Maybe someone have the same problem and find this helpful
