Hypercube 3D Printer - Adjustable/Extended Fan Duct (For clone/different hotends)

thingiverse

I built Tech2C's Hypercube, but the fan duct is too short for my e3D v6 Clone. Its blowing directly onto the heater block. If you decide to make one, please upload a make. I would love to see how yours turn out With this, the fan duct can be adjusted 2mm up or down by sliding the screw in the slot. At it's highest, it's the same as the default duct. At it's lowest, it's approximately 2mm below the default. I have mine adjusted to ~1.5mm below default. I also removed 2mm from the top of the duct, so it doesnt bottom out on the fan itslef, preventing movement. Note it may require a little filing. You do not want the screw's threads to engage in the slot. I personally have mine somewhere in the middle of the range. How I Designed This 1.) Opened Tech2C's fan duct in NetFabb Basic. I cut it directly through the screw holes. I moved one half 2mm away from the other. I removed the wall Netfabb generated (since it needs to be open, for air to apss through.) I exported each. 2.) Luckily and to my surprise, when importing into Meshmixer, they stayed 2mm apart. I expected to have to resituate them. I then made both solid, selected the face of one, and extruded it 2mm. I could in theory extrude this more to make it even more adjustable, but at that point it would be below the nozzle in most cases. 3.) I made it solid again in Meshmixer, combined the parts, made it solid again, repaired it in netfabb, then finally on my third "make solid" in Meshmixer, repetier decided it was printable.
