Fan Holder for Side Fans on Fabrikator Mini

These parts are for adding a Filament cooling fan on the side windows of the Fabrikator Mini aka Tiny Boy. I use two 80x80x15mm Fans, one on each side. They are connected to the "Fan" output clamp of the MKS Base. I can control them by S3D and it works perfect. I recompiled Marlin so that the heatbed clamp controls the controller fans for cooling the steppers and the hotend as soon as any axis is moved.
