The Mercedes Sprinter van body is curved in three dimensions. It's not just a flat panel with side-to-side curves. There is also front-to-back curvature. For this reason, it's almost bloody impossible to properly fit a screen to it through a process of conventional measuring. The only sane way I found to tackle this project was to repeatedly fit it step by step. Here's a general description of my process.
a custom hitch carrier that usually carries a Yeti cooler, blocking the street-side door from opening. Furthermore, the Yeti side of the van is where my husband sleeps, and he doesn't like sleeping with his door open, whereas I do. For these reasons, I re-designed this v. 2.0 screen to just cover my side, my door. This makes for a more manageable crafting project, and it also makes for easier administration of the resulting screen. For instance, if it starts to rain in the middle of the night, it's much easier to wrangle one door rather than two, in order to shut it quickly, especially when the hitch carrier is in place such that I have the rear step to use for this process.
|I laid the cut no-see-um netting on the polyester fabric and used it as a template for the first curved cut.|
|But then, of course, I had to basically trim off the remaining straight edge to create a curved strip of uniform width.|
|For instance on the bottom threshold, our 2006 Sprinter reveals this exposed, recessed bolt. Sure enough, I positioned a neodymium dot to attach to this bolt to help anchor the bottom edge.|
|Not a perfect execution, but presentable.|
