I'm not new to OpenBuilds, but new to posting here. When I typically build stuff, I just go through my OpenBuilds parts bin and try things out until it works. My challenge right now is that I'd like to build a custom machine from scratch for a product concept, and I'm not certain which plates' hole patterns work with V-Slot vs. C-Beam. Are there good resources for this, other than literally piecing real hardware together, or mating assemblies in CAD? I was going to start with engineering drawings so I could easily glance at hole spacing and other things. But it would be really nice if there were drawings that showed reference circles for the various wheels, so we could tell what works with what. Any advice would be really appreciated. I'd like to know how everyone else here starts out with a new design.
