80mm 2mm thick fan guard

thingiverse

To cool my X and Y stepper motors, I applied 80mm fans (http://amzn.to/2mxwORZ) while using these guards. These fans significantly reduced the stepper motor temperatures. The design is adapted from http://www.thingiverse.com/thing:128718 and customized via Customizer! (http://www.thingiverse.com/apps/customizer/run?thing_id=128718). The model features specifications such as mesh_clearance = 1, mount_hole_width = 71.5, mesh_density_ratio = 98, mesh_kind = hex, solid_outer_border = 5, mesh_holes_d = 10, mount_hole_d = 4.5, fan_side_length = 80, mesh_thickness = 2, outer_roundness = 50, and mesh_offset = 68 for optimal performance.
