Fan duct for E3D Hemera Hermes, can be mounted on any flat mount plate.
Is necessary to make some M3 threads, 2 for the 8mm suds on motor plate and 2 for the BLTouch (for Smart 3.1 BLTouch).
The fan is a std 4010 blower fan, the holes on duct for mount are 2mm so you can directly screw up the 4 M2,5 screws.
Plate Motor 2x 8mm M3
Duct to Plate 2x M3 8mm Studs and 2x M3 8mm screws
Fan to Duct 4x M2,5 6mm
BLTouch 2x M3 6mm
The offsets for the BLTouch Smart 3.1 are, from center of nozzle to front 42mm and to right 3.5mm, Z form nozzle to top 2mm
#define X_PROBE_OFFSET_FROM_EXTRUDER -3 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER -42 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER -3.6 // Z offset: -below +above [the nozzle] (in My setup, can vary slightly so must invidually tested)
The support on the Duct can be removed simply by hands
There are also step files if you want to remix ;-)
Added new remixed file Duct_RMX.st, is 2mm further away from the HeaterBlock and more parallel to bed
