Most of the BMG direct drive Designs are not "Direct" due to a small boden tube between the extruder and the Heatbreak. It is meant to lift the Motor on the X Gantry.
In this Design I made a slightly different approach, which is to turn the whole extruder and cancel the tube between the extruder and the Heatbreak.

This is Design meant to fit perfectly with the Geeetech A30 machines...

Build Material:
PETG or ABS is recommended, but PLA+ with some paint will also work.
You can get away with the normal PLA for some parts.
Since there is nothing to hold the wires anymore (i.e. No boden Tube), a cable chain is recommended.

Required Hardware:
2X M3x15
5X M3x8
5X M3x10
2X M3x20
1X M3x30
4X M2.5x13
12X M3 nuts

Changes in Firmware:
E-Steps: 415 for the 1/16 stepper drivers
BLTouch Offsets: X Offset 32 / Y Offset 5
Travel limits: Xmin -19 / Ymin -28

Any comments and/or ideas are very much welcome.

Update 15.01.2021: Added back screws like the seal for the Photon or Elagoo Mars. 
For this you will need an additional 20 Screws M3x4 mm. You might want to re-tap the threads. It depends on how accurate your print is.
