Clip - Suction Cup

I designed a Suction Cup Clip for mounting papers or as a hanging hook on the glass wall, to keep the wall clean without tape or glue. The structure is from the clip I designed before, which could keep tightly biting without metal springs. You can also download the clip free at: https://www.makeronline.com/en/model/Clip/25819.html You can buy the suction cup with M4 thread screw on Amazon, just search"suction cup M4": https://www.amazon.com/s?k=Suction+M4&ref=nb_sb_noss My other models: https://www.makeronline.com/en/user/personalInfo/e996b1df-bd17-4ed0-ae51-695a308ecce5.html Enjoy!
