Hot Air funnel for Flashforge Finder

The first part of a mechanism to blow hot air (from a hairdryer) onto my unheated build platform.

next parts will be the control arm to move this bit and the flexihose out of the way of the printhead.

Control for all this is done with an arduino NANO v3. driving the servo to move the head, switching the hairdryer on and off via a mains relay, and monitoring the 3 temperature sensors.

Next bit ( the really simple bit) - a small bit of code in the arduino to drive and monitor all this.
