Via Verde (Portugal) toll transponder cover box

This is a simple enclosure designed to fit around the Via Verde toll transponders used on Portugal's highways. It fits snugly around Via Verde devices - even ones you've already installed in your car - and camoflauges their ugly appearance without blocking their signal or affecting their function. Simply slide the large piece into place over your existing device wherever you've installed it and then slide the smaller end piece into place to enclose the exposed end. If needed, you can use a dab of light-duty glue or double-sided tape to hold the end piece in place.

Best printed in PETG or ABS so it doesn't warp in a hot car.

Kudos to @gigikoln3 for the motorcycle holder model that I grabbed the Via Verde device's shape from.
