qu-bd oneup twoup fan holder

screwless simple fanholder / fan fixing, which is missing in my printer kit.
after printing you have to cut an V (with side cutter) on the side where your cables get out of the steppermotor.
then attach like shown in the pic, without the need of screws...
printed with my oneup and with layer heigth 0,381mm
second version with thicker walls added. third version with already cut for motor cable on top.
