About this 3D model

Just a Lens Cap for my H9 Ultra HD 4K Action Camera from https://goo.gl/8CFfUF Don't know if it fits on other action cameras. It is for 21mm lens diameter + 5.6mm lens height. How to support me? Do you like my things and do you want to support me? You can use these links if you want to buy something. This helps me doing more things. Thanks!
