mini Satsana Dual 4010 Remix for Ender 3 v2

V1.1 Update: Redid some of the geometry at the front, modified the back for better and more enclosed hotend and cooling air separation and for better cable routing. It's a remix of the miniSatsana fan duct and hot-end cover for the Ender 3 v2 that uses dual 4010 fans and threaded inserts, compatible with the mounting bracket included with the CR Touch bed leveling sensor. It's divided into 3 parts for easier printing, and you can even use PLA, the constant airflow will keep it from warping too much. It uses M3*4 or 5mm deep 5mm wide heated inserts for the hotend cooling fan, and M2*3mm deep and 3.5mm wide for the part cooling 4010s. For screws youre going to need M3*12/25mm (depending on if your hotend fan is 10 or 20mm thick) and M2*8mm for the 4010 part cooling fans. The two inserts on the back should be M2*4mm deep and 3.5mm wide with M2*6mm screws. Print settings. Print settings for CURA: Smart Hiding of the seam, tree supports, 70 degrees overhang angle touching the buildplate worked very well.
