Hemera Mount and Cooling Duct for Ender 3
Description
This is a mounting plate, cooling duct and BLTouch mount for the E3d Hemera direct drive extruder on a Creality Ender3. Note the following: Because the mounting plate and the extruder move the nozzle towards the front of the printer the Y axis shifts about 18 mm. I was able to compensate for this by moving the the bed forward. This was done by drilling and tapping an extra whole in the aluminum extrusion the bed slides on and then using the existing back hole as the front hole and the new hole as the back hole. The cooling duct uses a 24V 5015 fan and moves more air than the stock fan so I've decreased my cooling fan speed. At some point I may redesign the cooling duct because it makes it difficult to see the nozzle while printing. Added a photo of the bottom of the printer. The arrow at the top of the picture points to the original hole. The arrow at the bottom of the photo shows the bolt going into the new hole I tapped and drilled.
