I upgraded my hotend for my Ender 3 v2 neo, but the cooling wasn't good enough to keep up with the newer print speed (I use klipper). I was running the Neo Solo shroud (before the hotend upgrade), and its excellent. However, I needed a new shroud to accommodate the shorter spider V2/V3 hotend. So I made one from scratch on cad, inspired by the Neo Solo.
One key aspect of my design is that the CR touch is embedded in the wall of the shroud. This was the solution I found for fitting another 5015 fan on the side, so the crtouch screws directly onto the shroud. This way, the bed leveling and bed mesh functionalities are not compromised.
From the CAD, the crtouch is 22mm offset in the X axis, and 1.1mm offset in the Y axis, you should be able to change the crtouch offset on the firmware, at least on klipper.
It doesn't use any heat set inserts. All of the holes are for M3 screws.
Also, you have to take the left fan cable off of its little strain relief, holder thingy. Or else its going to hit the printers left X axis cap. What I did was just to superglue the cable on the side of the fan, where it wouldn't interfere. You can see how it turned out in the picture below.
Another thing I did was change the side of the heater cartridge in the hotend. You should be able to just unscrew the grub screw that holds it in place and switch the side, because its cables are a bit thick, and were being squished by the crtouch. One downside is that you will also have to cut a sliver or a hole in the silicone sock, if you're using one.
Use ABS or PETG, or other heat resistant filament.
3 walls and 35% infill should be enough, but you can increase this, at the expense of making the shroud slightly heavier.
