I've installed this on my Hypercube Evolution and it is working well. I ordered my first spool of flexible filament and can't wait to try it out. Unless there is feedback that requires additional changes, I'm sticking a fork in this and calling it done.

Enjoy... I know I am.

I've removed the WIP on this design.

Updated the designs of the Extruder Mount, and BLTouch Mount.

Stand by changes are coming. Finally installed to my HEVO and what a rush. Although what's here will function, with rework, it will be easier if you wait for my changes.

Things being modified:

• Relief cut for extruder gear not correctly located. Gear rubs on right side and bottom of cut interferes with gear rotation.
• BLTouch mount requires additional adjustment range to allow adjusting to 8 mm offset from nozzle. (Shim designed as temp fix.)

I added new pieces.

• A BLTouch shim that can be scaled to whatever Z height is required to fine tune the BLTouch mount.
• A Loom Bracket to attach a loom the legacy Fan mount post. To mount to the current Extruder Mount you'll need to drill out the mounting hole in the post for a M3 screw.

Printed the mount and parts cooling fan mount. Based on test fitting made some additional design changes. Reprinted and test fitted to printer. It's looking very good now. Next is to print in PETG and ABS and test fully assembled functional install.

I have updated the Mount, Cooling Fan Duct, and BLTouch mount.

My changes up to now have been adjustments. What I learned is that the original design did not meet all of my requirements. I've taken a step back and did a version 4 of the design. Most parts changed due to new dimensions and alignments.

Design caveats due to the larger assembly with the Titan and motor:

• Probable loss of 5 mm on X axis.
• Possible loss of some Y axis travel.
• Probable 14 mm loss on Z height. (Trade off on Y axis losses.)

I will update after printing and testing.

See Design Updates for changes

I have been debating changing the Bowden extruder to a direct extruder on my HyperCube Evolution. I reviewed many designs and nothing matched all my requirements. I decided to design my own mount for two reasons:

• Design for my requirements

- Keep mass close to the X rails.

- Keep overall weight to a minimum

- X and -X endstops

- Accessible adjustment of the Titan extruder

- Canted hot end cooling fan (40 mm fan)

- Mount part cooling fan behind X rails (50 mm x 10 mm blower)

- Circular distribution of part cooling air

- Adjustable BL Touch mount

- BL Touch 15mm(spec) from heater block

(May decide to design new holder to move closer)

• Continue my learning curve on Fusion 360

Note: The original fan mount support is moved in this design to the right side of the bracket. I kept the support instead of deleting it because I use it as an anchor for the cabling loom.

This is a design in progress.

Parts that have been test printed:

• Fan Bracket - Good as of 5/12
• Hot End Fan Duct - Not tested to full assembly
