Toll Pass Transponder Case

I designed this case for my FasTrak transponder because I couldn’t find a clean and convenient place to mount it.

• Sticking it to the leather dashboard was a hard no.
• Mounting it on the windshield with adhesive wasn’t an option either — I didn’t want to deal with glue residue later.

So I made a removable solution using a suction cup. The transponder sits securely in the case, mounts to the glass, and can be removed in seconds with no marks left behind.

Assembly Instructions

1. Remove the original stickers or adhesive from the transponder.
2. Insert the transponder into the case.
3. Attach the suction cup. 

Material Choice

The case is printed in ASA, specifically to withstand high interior car temperatures and prevent warping in hot weather.

Note on the Suction Cup

I can’t 100% guarantee that the suction cup linked will fit perfectly.

I used one I already had lying around, but based on the photos and dimensions, it should be compatible.

Designed for practicality, heat resistance, and a clean interior — without adhesives.
