UPDATE: Note that https://www.thingiverse.com/thing:2985547 is the final form of the idea, as it combines a superior fanduct with a much easier and modular mounting option.

Evolution of earlier design with SG90 servo. This one is optimized for MG90, bringing much better repeatability and accuracy. Sample test run, without and with probe store:

CLARIFICATION: the dimensions of this model have been designed with the TowerPro MG90S servo in mind. Any servo that has the same physical dimensions is fine, YMMV if you use anything different. Example MG90S servo: https://www.amazon.co.uk/Micro-Compatible-TowerPro-Metalico-Arduino/dp/B073WZD36H/ref=sr_1_3?ie=UTF8&qid=1517642668&sr=8-3&keywords=mg90s
