About this 3D model

This cooling duct fits around the hotend case of the Tronxy X3 printer with a bed leveling sensor, as shown in the picture. It is designed to fit snug on the metal cover of the hotend without any screws or fasteners. The size of the area inside is 48mm high and 46mm wide so it can fit on any other printer with the same size hotend cover. The blower that I am using in the picture messures 50mm high x 50mm wide x 15mm depth. It also needs 2 x M3 screws, 20mm long.
