About this 3D model

Print with the outlet end facing down when printing. It is recommended to add 2 to 3 raft layers to avoid elephant foot effect causing the friction pad and outer wall to stick together. The Z seam needs to be set outside the friction pad and the bottom surface. If the Z seam is between the friction pad and the outer wall, after printing, you may need to use a small flat-head screwdriver to gently pry the friction pad to separate it for normal operation. Top Spin requires an M3×2 machine screw.
