Foam board Mounting Clip

SummaryThis clip helps to mount foam board(5mm thick) on the glass wall with a suction cup of M4 screw.The M4 thread has been preset on the model so it's no need to buy an M4 nut. In order to fit the M4 thread well, 0.1 layer height is recommended. You can buy the suction cup with M4 thread screw on Amazon, search"suction cup M4":https://www.amazon.com/s?k=Suction+M4&ref=nb_sb_nossPost-Printing The first version with no concave-convex structure, the corner is loose Then I add concave-convex structure on the corner, makes the 2 parts connection stronger
