About this 3D model
Changes done to the original: Flattened the tip of the lower mount to allow it to fit onto the MK3S properly. The side screw could not be inserted on the original. Lengthened the mounts to lower the duct by either 2.0mm or 2.5mm. The original did not sit low enough to blow on the part instead of the heater block. I am using the 2.5mm drop with my MK3S+ and E3D Revo. Some sharp edges have been filleted.
