Hemera V6/ Volcano Part Cooling Duct & Mount

cults3d

A 5015 part cooling solution based on tried and tested CFD analysed and optimised part cooling air flow. It's designed to give a high speed converging flow that doesn't blast the heater block or the print bed, and once past the tip of the nozzle exits cleanly to the rear. Parts print in the orientation as downloaded. The duct prints with no supports, and the mounting plate with supports from buildplate only for the M4 nut recesses on the back. When assembled the underside of the duct should be 1.5 - 2mm above the tip of the nozzle. There is +/- 2mm of vertical adjustment. Note the orientation of the heater block in the images. Although it fits the other way around, it is then too close to the duct for comfort! Hardware required is 1 x 5015 blower. 2x M3x10mm bolts 2 x M3 washers 2 x M4x25mm bolts 2 x M4 washers 2 x M4 nuts Any queries just ask, and if anyone feels a bit more information is required then I'll keep this updated. 12/12/19: Mount plate STEP file added for easier remixing. 12/12/19: Volcano duct added 17/1/2020: I've added a revised V2 mount with an extra 3mm of upward adjustment for those users who are having trouble getting the correct clearance between the underside of the duct and the build plate with the original version. 13/2/2020: I've made a small tweak to the duct design to get the highest speed flow to coincide with the tip of the nozzle.
