This is a mobile phone adapter that fits an Arca-Swiss style tripod mount. A rubber band is needed to keep the base and slide parts together. The groove in the bottom is preventing the plate from accidentally sliding off the platform on Sirui tripods, which have a safety pin and release button on the platform. Note: The printed parts in the photos are slightly different than the final 3D models. | Download free and paid 3D printable STL files
