Universal Bike Phone Mount

A bike phone mount designed to utilise an in car air vent phone holder.

I already had the difficult part, the bit which holds the phone securely, so I decided to only model and print the adaptor part. A phone mount for air vents can easily be found online, e.g. https://www.amazon.co.uk/Venti-Airmount-Portable-Holder-Smartphone-White/dp/B00LB1V1KU/ref=pd_sim_107_1?ie=UTF8&psc=1&refRID=ZHW64QQWEXJW754QF6WF

Here's a link to my model should you wish to adapt it:
