Before the modules can be put together backplates are needed. The backplates for my other modules don't match up for what is needed on the EQ modules, so features of each module needed to combined, and holes needed to be moved to compensate for how much stuff needs to fit in these.
This CAD was made over a year ago and was much based off of what could be seen on the Clapton modules. Lens distortion and angles prevents one from being able to just use the photo on it's own. Recently, I added the tabs that you see.
