CRAFTRUMs Direct Drive with BMG extruder and E3Dv6

PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
__UPDATE 9.6.2022__
I've fixed some tolerances of the duct so it fits easier into the base part. Also, I've noticed some aluminium carriage plates are even thicker then 3.1mm (because of a rough surface painting). I've added the base parts for carriage plates that are 3.3mm thick (best is to measure your plate on the printer with a calliper before choosing the right version to print).
<h1>OVERVIEW</h1>
This is a FULL DIRECT DRIVE (NO BOWDEN NEEDED!) for the E3D v6 and BMG extruder. The mount fits the standard carrier found at TEVO, CREALITY, and many other printers. I've tested it only on a TEVO Tornado and Ender3, but it should fit on any printer with the same carrier - see attached photo.
The following guidelines were considered when designing this extruder mount:
- it should be a full all metal direct drive (with no bowden at all)
- reduced cloging
- optimized airflow under the nozzle for good bridging
- reduced airflow to the heating block
- a good cable management solution
- accessible nozzle for an easy nozzle replacement
- easy attachable mount to the carrier
A CFD (Computational fluid dynamics) analysis was done to optimize the airflow in the Fanduct. The "water test" shows the concentrated airflow under the nozzle --> https://youtu.be/EFtvNRnnMN0
