This is a remix of the awesome Velocity Stack and Fan Guard for 40mm Fan (round)
by admodesi (remixed with permission, I claim no rights to the creation of the concept/modeling). My version has been scaled down for use on a 30mm Fan like the one used on the Monoprice Select Mini. The screw holes have been resized as necessary so the stock screws will work for attachment to the outside of the fan.
Please check out his original design if you have done the 40mm fan upgrade on the MPSM!
Set bottom, sides and top to 0.8-1.2mm
