Fan Guards designed for Almond Lee's Printrbot Play shroud: All the STL's have been run through Netfabb Cloud, so they should be valid. As far as print settings, I suggest minimal layer heights (~50 micron; 0.05556 mm Layer Height in Cura for the Play), 100% infill, and slow printing (30mm/s). Fan Guard Iris_fixed.stl is something of a torture test... 

Classic grilles are available in ring thicknesses of 0.2 to 0.8mm. Use whatever slices best for you. I find that for a 0.4mm nozzle (included with the Play), Cura slices the 0.6mm variant easily, while the 0.4mm variant requires tweaking of the shell thickness to get a decent slice.

I make no guarantees about safety! Use at your own risk!

I have not evaluated the airflow characteristics of any of these grilles.

Changed name of Classic to reflect the need for a 0.2mm print nozzle.

Replaced "2" with "Iris". Iris adds a center ring that eliminates some craziness where the fins/ribs intersect. Should be much more slice-able/printable.

Republished Fan Guard Gear. Interior of original was rotated 5 degrees from orthogonal.
