A mounting for a blower similar to this http://www.asia.ru/images/target/photo/51549099/DB9733_Blower_Fan.jpg I made it for Vellman K8200 printer to keep stepsticks cool after turning up the current limits. The diameter of the blower air intake is 50m, its 27.7mm thick and the distance between centers of two mounting holes is 81 mm, It is meant to be attached to the Vellman K8200 original fan holder using M4 screw (the hole in part lin3.stl is meant for M4 screw, its diameter is 3.8 so the screw will cut into material). By combining link2 and link3 parts you can achieve more degree of freedom. List of printable and non-printable parts is in "Instructions" section.
