Sucker cup extension for Anker ROAV A1 car DVR

Anker Roav is a great dvr. it's suction cup mount is great as long as the windscreen is mounted at angle- like in every car. but there's a thing- there's things called lorries, trucks etc, and their windscreens are mostly vertical. Here's the extension- bare minimum required to set camera pointing straight forward and not at the ground. Needs a bit filing/sanding for the tight fit. I printed mine with PLA 95%infill but 100% will be better. You will need 3mm bolt [22mm]+nut
