Tollway Sticker Tag Mount for E-ZPass / I-PASS

I keep two tollway tag devices in my car to handle both personal and business trips. The unused device lives in an RFID faraday shield bag in my glove compartment. It's a simple matter to swap as needed using the heavy-duty velcro strips on both devices and on my windshield.

My home state of Illinois has begun forcing a change to a sticker tag that can't be removed from the windshield. My solution is this mounting plate for the sticker with a place for velcro strips that match the spacing of the physical units. The sticker is still only usable for the vehicle it's registered in, but I can continue to easily swap it out for my business tag.

For those who may be wondering, I am able to use two devices registered to the same vehicle and license plate by getting them from different states. Most states are happy to let you register and get a device from out of state. The personal tag is from my home state of Illinois. I chose Florida's SunPass PRO tag for my business use since it covers the most states. It appears that the technology to cover all of those states will still require an electronic tag for the foreseeable future. But if everything changes to stickers someday, then I can simply print more sticker mounting plates.

Important: This will need to be printed in a filament that can take the high temperatures in a car on a sunny summer day. PLA is not a good choice for this. I made my first print in PETG but it warped on a hot day. I would recommend ABS or Prusa's PC Blend. My reprint with PC Blend is holding up well.
