** UPDATED FIRST PAGE ** Greetings, I've been working on this for a while and only recently started strolling in the Radicons forums to see some of the amazing work here. I'm working on creating a transformable trailer for my Jetwing Prime. The plan at this moment is to model it in 3D and have Shapeways print it, then I can paint and assemble. Here is the latest print, the pieces to assemble OP's cannon from DOTM. I plan on making this available soon for those interested. It will be available in my Shapeways store. Initial test assembly came out extremely good. All the hollowing out to keep costs down worked very well.
