I had a tough time finding a good place to mount my front and rear facing Polaroid Cube cameras on the Milan SL so I came up with this temporary back to back camera mount. I’ll use this until I can come up with something better. This mount is attached to the left side window. Here are some views of the design in Fusion 360.
Each camera has its own microUSB cable that is fed to a battery pack / charger. Here it is in real life on the Milan SL. I didn’t spend a lot of time smoothing and painting it since I consider it a temporary solution.
I’ve since gotten rid of the Polaroid Cube cameras in favor of a dedicated motorcycle dash cam system. This required re-designing the camera holder for the smaller, lipstick shaped cameras.
