And here is my asymmetrical IDEX. On the left is a Mosquito with BMG-M extruder and on the right is a generic v6 heatsink with E3D heater block and temp cartridge and a regular BMG extruder. Both have genuine E3D 0.9 degree pancake stepper motors that came out of genuine Titan extruders I bought in projects past. I still have to make some pieces to bolt the cable chains to and get the belts installed and then get it all wired and programmed so I am not done by any means but I have 2 extruders on one gantry and that is progress..



And I did not design the mount for the fans on the v6 heatsink. I used the easy button and took to Thingiverse and searched for something that fit my needs. I was impressed with and used this design for that. It saved me time and is a really good design and I got it right here:
