A super cool aperture structure has 5 stl files: top cover, door panel, slide rail, rotating mechanism, fixed cover, door panel and fixed cover need to be printed 6. It is recommended to print 8 door panels (easy to cross the edge, more spare) Note: the gaps between the active mechanisms have been adjusted, there is no need to set the horizontal expansion. It is recommended that the top and bottom layer are set 0.6mm, and the wall thickness is 1.6mm
