About this 3D model

update 02/06/2014 small problem with heat when i print over 4 hours, so i angled the fan lower, plus i made some clams for the cables (Fan-MountV6) ----------- update 29/05/2014 still some noisy, os i switched to my 80mm fan, no more fan noisy :) (Fan-MountV4) ----------- i changes Nostromo82 Printrbot Simple 2014 Fan Support, for some reason i got a lot of vibration that made the fan noisy, so i change the model to fix it
