NF Crazy - Ender 3 - DUAL Blower and Mount

Mount and dual blower for the all-metal hotend NF Crazy (Generic Mosquito).
*I personally use the BLTouch Version

This project I worked on for months, designing 22 versions of the dual blower and configuring my printer. I can say that I can now print PLA, TPU and Carbon / Nylon with no problems.

This is not a project for beginners:
You have to 3D print the parts in PLA to start and then Carbon when you are done.

Before starting this project you should watch videos like:
All Metal hotend microswiss by Teaching Tech! - Thank you Teching Tech!

For Carbons or high-temperature projects you will need Marlin or a board that can be modified for higher temperature settings and adjustments for the thermistor and heater block/heating tube:

You will also need to trim the offset.

Settings:

Supports are needed (CURA blockers on the blowers and all bolt holes)
Print with the blowers pointing up.

Infill 25% - 45% the higher the infill the stronger the parts.

I have a direct drive on my Ender 3 - A STOCK Ender does also work, verify mounting holes first.

Phase 1: Mount the Hot End Cooling fan into the Blower Assembly
Phase 2: Mount ONLY the Right cooling fan into the Blower Assembly
Phase 3: Mount the Support Assembly to the mounting bracket
Phase 4: Mount the NFCrazy to the Support Assembly.
Phase 5: Mount the Blower Assembly to the Mounting Bracket
Phase 6: Mount the Left cooling fan into the Blower Assembly
Phase 7: Zip tie your Thermal and Heater wires to the Support Assembly
