EZPass Privacy Box Slider - Faraday Cage

Inspired by rental car boxes, this privacy box is designed to block your EzPass from reading while not on toll roads. This blocks a tracking vector used to violate your privacy. You can't stop companies and governments from stealing your data via license plate readers, but no need to make it easier for them. You'll need copper tape and velcro for this project, which you can likely find at your local hardware store.

I recommend printing with PETG or another material that won't melt/warp if you park your car in the sun. I printed with supports. Assembly requires metal tape to provide the actual shielding action, you should wrap the entirety of the outside box with copper tape (or the metal tape of your choice), preferably multiple times. This is what actually prevents the EzPass from being read. Then, you slide the box open while using toll roads.

The box should be mounted so that the open side faces the window, and so the box can't fall out when open. I recommend mounting with velcro so you can remove/reattach the holder.

Created with OnShape. If you'd like to modify the model, you can make a copy or export to your desired format from the public document page. This was designed for recent EzPass MA versions, you may need to remix if your EzPass isn't the same size.
