If not for my current engagement with a race against the clock and the resulting manic situation, I'd offer to do the modeling work for you. As it is, I'm working flat out while symultaneously preparing for a very long-distance move. This situation has forced putting the construction of my own mid-bass horns on hold.

Autodesk, the parent company for various CAD software applications, offers a free 30-day trial of AutoCAD as well as just about every one of their products, amongst which, there are several NURBS and subdivision-based CAD apps. Not all are listed on the "trials" page; use the search function to find a specific application if not listed (under "All Product Trials"). It is unlikely that trial versions will allow saving your work, but you may find a way around that, especially as your main objective will likely be a printed version of the plans. Unfortunately, Autodesk's downloads require installation of their "download manager/installer".
