Single-piece filament Y-switch for e3d pushfit connectors.

So I decided to give dual extrusion a shot using just one nozzle and it actually works like a charm. I've taken a look at other Y-guides, which got my creative juices flowing, but for some reason, none of them clicked with me so I designed my own from scratch. Luckily, it's not too complicated. This custom Y-guide is a single-piece print that requires no support material and offers plenty of flexibility if you need to make any adjustments down the line. However, since it relies on threads.scad library, I opted against making it customizable through a customizer tool - mainly because it would've been a bit too much work. Now, when it comes to actually printing with this Y-guide, things get a bit more complicated and depend heavily on your specific firmware and slicer setup. Sorry, but you're pretty much on your own here. If you do decide to give this a try, just remember to render the scad file one last time with `draft=false` to get the best results.
