Zafira mount
Here is a my 2nd version of a mount for a Zafira air vent. May fit other Vauxhall models.
This version fits a lot tighter into the vent.
Fell free to edit the attachment to fit your own kit.
I suggest printing in ABS. since my PLA version warped on a nice sunny day. Car got very warm.
This thing was made with Tinkercad. Edit it online
