I created a base modification off of the following files and remixed/added some additional distance for USB plugs on the backside. This modification was to allow for future baseplates to be used to adapt to anyone's printer (cross bar, or table top, etc.).

3 files include -

BTT-PAD7-Mount
Clamp Extension
PipeClamp
Again, the clamp extension give approx another 60mm of space from the back of the mount to the start of what every base plate you choose. If you have special base plate requests, let me know.

For the pipe clamp - it was not rigid enough to hold it into place so I added some 2-sided strong adhesive tape to grip. This was my solution because I mounted it to the sewer drain pipe in my basement (and the pipe was tight against the wall so a full wrap around clamp was not an option). - you can see it in the photos.
