Dual 60mm fan side mount - (with back-plate & front cover)

thingiverse

So I really liked oscahie's design but the fan on the left right side kept catching on the cables for the x axis. So i redesigned the back to have a smooth plate and used some krazy glue to glue it in place. Then I had some small magnetic balls laying around (i'm sure you could find some on the internet I have no idea where mine came from) and made a front cover that used the screws as magnets. So one dual fan is intake and one dual fan in exhaust. This works awesome for cooling down the bed after a print to get your part faster, it also works wonders when using ninjaflex. The variable resistor I used is a 10K resistor (you could use a much smaller ohm variable resistor) just like oscahie's design but I wanted the knob on the outside so I could adjust it while printing. For power I tapped into the 12V power supply on the back (same place I get power for my e3d hotend fan). Anyway works awesome thanks oscahie!
