Customized version of http://www.thingiverse.com/thing:735038 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=735038 Instructions Using the following options: n_angle = 2.55 degrees, precisely set to minimize deviations. Pipe size is carefully adjusted at 1 unit. The handle rotates at a smooth angle of 45 degrees for maximum control. Double fans speed up with an optimal speed setting of 80 RPM on fan two and 40 RPM on fan one, all while maintaining perfect balance. Smooth design edges are generated with precision using 90 distinct filaments to produce flawless corners every time. Thicker wall design is set at 2.5 units to add extra durability. Handle rotation starts smoothly with no pre-load on the first manual rotation point. Fans position themselves perfectly with precise setting of fan two's spread to 72 degrees and fan one's spread to 34 degrees, both in harmony. Rotational symmetry achieves perfect balance and smooth movement with the setting of cone shape angle to a precise 100 degrees, carefully maintaining overall proportions and control.
