I have modified the original mount by Johnygab for use with a Titan Extruder (the original anet A8 extruder should work fine to) the cutout next to the extruder mounting spot is for the titan extruder's large gear.
I have made the mounting spot thinner and added walls on the sides.The stepper motor fits snugly between the walls.
When installing the Titan extruder use the M3 x 12 and two M3 x 30s then one M3 x 35 with the lock washer.
There is a version with the normal anet a8 lcd backplate holes and one without those holes.
The large flat surface is the bottom.
If you have simplified 3D use 2 outer layers and I suggest splitting the process up at 4.0mm with the plate being 25% infill and the mounting spot be 100% infill
