Micro Swiss Compatible Hotend Cooling for Ender 3v2 - v1 by RedWhere2020

This is now an outdated model, look for v2.
v1.
Two changes were made... 1) fan screw hole sizes reduced and 2) the parts cooling nozzel width reduced for better side viewing angle.
Designed this for those requiring a basic and reasonably compact Micro Swiss compatible hotend cooling duct modeled off Crealities Ender 3 OEM fan shroud with part cooling pointing either side of the nozzel using the two stock fans.
You need to thread tap the top two v-slot roller mount holes on the front of the Micro Swiss extruder plate for this to mount.
This has a y-axis adjustable mount for a BLTouch and conveniently has two cable restraint locations. Dont forget to change the XYZ offsets as the BLTouch is on the right hand side of the nozzel. X offset is +31mm and Y offset is -8mm (but adjustable) with the Z offset being -4mm, but this can be adjusted with packers.
I mounted the hotend cabling so it routes to the front and left side using the angled cable restraint on top with the cable passing by the x-stop cover plate. This is so the cable does not get bound up in the top cross member extrusion when the Z-axis is high.
Added stil file of the cable restrint that mounts to the x-stop cover.
I printed in PLA+ for testing purposes but would recommend PETG or ABS to handle the heat from the hotend. Has 2-3mm clearances from the silicon sock.
2/M6x8mm button head hex socket bolts.
1/M3x8mm button head hex socket bolt.
Works for me!
