FasTrak Holder
thingiverse
Made this to hold a Fastrak Flex toll tag (https://www.bayareafastrak.org/en/about/toll-tag.shtml). I originally designed it so I'd have to way to mount the tag on my motorcycle, but it also works fine on a car/truck windshield. Has a gap wide enough in the middle to change the occupant number switch without having to remove the tag. The "dimple" and switch on the Flex tag isn't in the middle (lengthwise) on the tag. The holder is designed for it to be inserted "longer" end first. Printing: No special requirements, although use of PLA isn't recommended as it'll be either exposed to UV (on a motorcycle) or heat (a car interior). I used PETG for printing mine out and it works great.
