50mm print fan / blower guard for Prusa i3

thingiverse

New for version 2: In certain cases, the original bolts were too short with the guard attached. The thickness under the bolt has been decreased The bottom edge features a straight cutout so that the guard doesn't touch the duct for the print fan Bolt heads sit flush for a cleaner look The surface in the STL is solid - you can modify the slicer to make the mesh. This results in faster prints, reduced material usage, and improved airflow since the mesh lines are all a single line of material. To print, set your slicer to zero top and bottom layers, and use a suitable infill such as honeycomb. Increase the number of perimeters until the guard has a suitably thick edge. ABS gcode is included with the proper settings for a honeycomb grille on a Prusa i3mk2. Guard for the blower on the front of the extruder of an i3 mk2. It can also cover any 50mm blower (the i3 mk2 uses a 5015).
