Prusa MK3S+ and MK3.5/S Fan shroud

Fan shroud for your mk3s+ and MK3.5/S inspired by the old MK3 fan shroud. Original mod was from @Technoid_13862 then remix by @Jara_454860 to add the original mount position and reremix by me to remove the 2 additional mount position and only keep the original position. Wich make the part simpler and easier to print in nylon or PC. On my mk3.5s it throw an alarm during the fan calibration because i think the airflow of this shroud is a little more restrictive than the stock one and it make the fan turn just a little bit slower than it can/should. So i just unmount the fan from the shroud for the time of this calibration. So yhea it is a little more restrictive than the original MK3s+ fan shroud but imo the air flow is way better distributed around the nozzle
