Ender 3 V2 Neo Shroud for 4020 fan
thingiverse
I had an issue with the hot end overheating, decided to upgrade to 4020 fan. Was not able to find any shroud that I really liked. Used "original" STL to get tabs positions. Everything else designed from the scratch. Requires 3 threaded inserts M3 x 4 x 5mm (https://www.amazon.com/gp/product/B08NJP5V1M). I used this Winsinn 4020 fan but pretty much any other will work (https://www.amazon.com/gp/product/B07L3CT33J). On the Ender 3 - print slowly due to a lot of small details. No supports needed. New fan cools really really well - PID recalibration may be needed, silicone sock is really really recommended. Enjoy! UPDATE 1 Uploaded new V2 - moved fan 8mm up (better heatsink cooling, less air blows on a heating block, also pushed fan 1mm closer to the front - little bit more space for bolts / washers / wire.
