Car cable holder for windshield dash cam

Had a problem that the cable of my dash cam kept falling out from the gap between windshield and the panel. Designed this snap in holder that holds the wire and squeezes in the gap between the windshield and the panel. The end that goes in the panel gap squeezes a bit and pulls out easily without damaging the panel, because of its rounded ends. 

So far it holds well and has not fallen out. Could make iterations for wider cables and wider panel gaps. 

Feel free to let me know if different sizes are needed. This is for a cable 3 mm wide. 

I printed in PLA but probably you should do PETG or something with better heat and UV resistance.
