Ran into my first build snag; this might be a result of my printing process (I had to print to .pdf and edit the layout in GIMP to fit Letter size), but the laminate panels on the track segments are just a smidgen bigger than the outside face (on the length, not the height). This could be resolved once the form is built, if not I'll just trim to fit.
I've made no 'build' progress yet, as the lamination panels are still curing, just setting up the parts, folding and trimming so that the final build goes smoothly. The bits are laid out very nicely for building, and Pep Viewer 3 is awesome as you can isolate view every mesh in case of questions. I've played with some things too, cutting out the side doors and trimming them a little to get the feeling of depth once fit back into place.
Thank you again!
