120mm Fan mount for LACK back leg

I needed a way to mount a ventilation fan on the LACK enclosure for when printing ABS and other materials which creates fumes. This model is intended to replace the top left leg mount and requires a few extra screws, and also cutting the back plexiglass a bit to have the fan mount. Made for standard 120mm PC fans. 

The model is oriented in the way it should be printed which shouldn't require any supports.

0.2 mm layer height.
