Why?

Tension bolt is free!
BLTouch doesnt need 'special' long curved mount - its just below e-motor - on the same plastic part,
Duct is ~13mm from nozzle, Fan ~16mm from nozzle, close enough to cool down things.

i didn't find ready to use designs, so...

Additional parts (not included with Titan and stock Black Widow)

2xM5x20 bolts and nuts to mount base (it uses 4xM5 bolts) - flathead preferrred, 1 flathead is required if u will use attached duct (read assembly)
(optional) 4xM4x30 (or longer) bolts and nuts for model duct
(optional) Single 50mm 24v radial fan (can be ordered here)

BLTouch

BLTouch mount is in the base, if u use it - no additional mount is required, if dont - u will have some unused holes.

Marlin (1.1.8) offsets is

#define X_OFFSET -26
#define Y_OFFSET 29
#define Z_OFFSET 0

Old style

#define X_PROBE_OFFSET_FROM_EXTRUDER -26
#define Y_PROBE_OFFSET_FROM_EXTRUDER 29
#define Z_PROBE_OFFSET_FROM_EXTRUDER 0

HotEnd

Designed for Original Tevo Black Widow hotend which goes with Tevo Titan Extruder.

If u have original E3D hotend (https://e3d-online.com/v6) then heater and thermistor wires
will go toward to u, which isn't very good, but if its ok - this mount will do the job.

Volcano - not tested - but may work, if u try and it will work - msg me please.

Materials

Better to use ABS for all parts

Base - ABS (better) or PLA (will work) - both tested, but PLA will deform eventually due to E-motor temperature
Hotend Duct - ABS only - PLA will deform - too close to heater
Model Duct - ABS, PLA may work (~9mm from hotend) but not tested
Model Duct mount helpers - ABS or PLA

Printing

Hotend Duct - AS IS, no supports, ooze shield for better results, 0.2mm
Base - rotate on X axis -90 degree, use supports and ooze shield for better results, 0.2mm
RDuct - rotate on Y axis 90 degree, use supports for better results, 0.2mm
Model Duct mount helpers (2pcs) - rotate on X axis -90 degree - ooze shield for better results, 0.2mm

Assembly

1. Print hotend duct (NO SUPPORTS)
2. Print base (use supports as it has one big hole for E-Motor, or place it manually)
3. (bltouch only) Mount BLTouch into the base
4. If u plan to use duct - place 2 M4 bolts into second row (from top) on the right side of base (check photos)
5. Put E-motor
6. Mount Titan extruder with E-Motor by screwing 3xM3 bolts (included with titan)
7. Mount Hotend duct (see photos) - it must fit tight into radiator (see photo #4)
8. Place wires
9. Mount base (read below if u plan to use duct)
10. (bltouch only) Update firmware (google how to)

(optional) If u will use duct

1. Use FLATHEAD for right bottom bolt when mounting base (see photos)
2. Print duct (using titan already) - duct requires a little bit supports or model fan
3. Place radial fan on duct
4. Put nuts into two helpers
5. Mount duct using helpers - dont tighten nuts now
6. Calibrate duct height - it must be ~2mm above the nozzle
7. Tighten duct mount nuts
