Diplo Duct - Ender 3 V2 4020 BMG Direct Drive

Here is a cooling duct I designed as I couldn't find anything to suit my needs.

My requirements were:

• Use 2 4020 or 4010 fans
• Direct drive with BMG

• Stock hotend
• No loss in build height and XY dimensions
• Great access to heater block
• Voron inspired ish :)
• BLtouch mount
• Cable chain

I've uploaded a zip file that contains STEP files as well as some models with supports and or heat inserts.

BLtouch offsets: X= -46 Y= -17

I used 19 links in the cable chain

Top fan is for the hot end cooling and bottom fan is for part cooling.

Nozzle height can slightly be adjusted with the Stock hotend by loosening the grub screw that holds the heat break if you need to raise or lower it.

Let me know if you have any issues and ill adjust the design.

Feel free to ask any questions if needed
