This is hotswap edition of my mount (https://www.thingiverse.com/thing:4316649) - easy to swap between v6 and volcano hotends via 2 M3x30 screws. You don't need to disassemble anymore Titan extruder to swap.
Height of fan ducts from the plane of the nozzle about 2mm.
You should use hotends with only full-metall heatbreaks.
Also you need to install an bowden adapter on titan extruder without PTFE clips and holders.
There is *step file for convenient editing for you purposes and dont't forget to share you remixes :D
You can use any fan mount for heatsink - I use https://www.thingiverse.com/thing:354723
I do not promise that a mounts BLTouch/EZABL/BFPTouch will be added.
Update 09/20/2020 - fixed M3 Nuts holes (added Frame_v2)
Версия моего обдува (https://www.thingiverse.com/thing:4316649) с фунцией "горячей" замены хотендов - достаточно открутить 2 винта и можно заменить на другой хотенд.
Поддерживаются как v6, так и Volcano хотенды.
Высота рукавов обдува от плоскости сопла около 2мм.
Использовать хотенды только…

This is remix from Heavy Duty e3dv6, but with more stable Bltouch.
Аll original modules from HeavyDuty fit with my remix
