Every time I buy a new phone, I need to get a holder for it in the car too. Regular holders aren't very practical and often break easily. I've decided to put an end to that by designing a simple holder that will fit any kind of sucker. Now, all you have to do is enter your phone's dimensions and maybe play around with them, and you'll have a brand new holder! Since the plastic is quite stiff, it's also possible to adapt this model for phones with cases on them. Printed with ABS. Please adjust the sizes for your phone, plastic, and printer in the OpenSCAD script.
