About this 3D model

This is my original design of mobile phone car holder, this bracket can be freely replaced in other occasions, such as: toilet wall, kitchen wall, bedroom, computer screen. This design is still under design, there will be more optional parts. Assembly instructions video address:https://youtu.be/KUK7bn-TC2M There are two schemes for springback. If there is no spring, rubber band can be used instead. Of course, the effect of spring is better. The STL file of the base part is in another website: https://www.thingiverse.com/thing:4568218
