Car-Phone-Cup-Holder v1

thingiverse

An upgraded version is available now. This phone holder is suitable for cup-holders with a diameter of 68mm or more, along with phones that are no thicker than 12mm, including their cases. The STL files include 'base', which is the cup-holder part, and 'hooks' - two lower hooks that attach to the base and two upper hooks linked to the lower ones via rubber bands or zip ties if necessary. I only needed the lower hooks, friction welding them into the base's slots for assembly. To learn about friction welding PLA, check out this link: http://makezine.com/projects/make-34/skill-builder-finishing-and-post-processing-your-3d-printed-objects/. However, I made one in black PLA and found that the base had warped due to heat or sun exposure inside my car. Therefore, it's recommended to thicken the base or use ABS instead of PLA, or maybe white PLA/ABS for better durability.
