Hotend Fan holder for Prusa X Carriage with LM8UU holders and E3D v5 hotend
Description
I Tried To Fit Stock [E3D V5 Hotend Fan Assembly](Http://E3D-Online.Com/E3D-V5-3Mm-Direct-All-Metal-Hotend) Under [Reinforced Prusa X Carriage With Slim Lm8Uu Holder](Http://Www.Thingiverse.Com/Thing:18657) Without Much Success. There Is Simply Not Enough Space Between The Lm8Uu Holders. Therefore I Designed This Duct/Holder, Which Connects To The 15X10X10Mm Accessory Mount Point On The Carriage, And Allows To Suck Away Excess Heat From The Hotend'S Heatsink. Since The Fan Is Further From The Heatsink, It Is Less Efficient. Still, I Tested Cooling From 200Deg.C To 60Deg.C With And Without The Fan Running, And The Cooling Time Is 4 And 8 Minutes Respectively. So This Arrangement Is Still Ok, Efficiency-Wise.
