30mm Fan Clip-On Guard/Grill

I love the 40mm Clip-On Guard Yakulis created. This version covers the 30 mm fan sitting in front of the Wanhao Duplicator i3 and it's variants such as the Monoprice Maker Select. Simply reducing the 40mm guard size does not work as there are four bump-outs lifting the grill away from the fan. On the 30mm fan, two of the bump-outs hit the screws. The offending bump-outs have been removed making room for the screws.
