I am new to the 3dChameleon and have bought it for my ender 3 pro, I'm currently stuck on the first step because I cannot fit the coupler into the extruder. Is there a specific mount for the ender 3 pro? I have tried the ender 3 one and it didn't fit.

I made this Thang to maybe help with this issue.
The idea is it screws into the Dual Gear extruder (you might have to close the spring slightly). The the spacer passes the z rod and the end can accept your Bowden coupler. The bowden tube should flow all the way through this device. It is still a work in progress and it is suggested to print at .08 for the thread detail. Hope maybe it helps someone.
I printed all the ender mounts and it is combination of things. The z axis is definitely in the way. In addition, with the dual gear extruder the filament whole is not really aligning with the other side. My tinkercad skills are weak, I did see the not of using a hole to current out more. I fear I would have to cutout into the bowden tube hole or extremely close. If I have some time. I will try and share my results.
I have the same issue with my ender 3 pro and the dual gear extruder with bowden tube setup. I am thinking of turning the extruder 90 or 180 degrees. Not sure of the potential risk. I will post what I find in testing.
We have several adapter plates for the Ender series of printers. Check out our Tinkercad page for some that might work. I don't know which specific extruder your printer has, but they're all pretty similar and easy to adapt to.
