Toll Road Transponder Suction Cup Mount

thingiverse

To keep your transponder tag clean and organized, use this specially designed holder to attach it instead of sticking it directly to your windshield. This approach eliminates mess, makes it easy to store, and allows you to transfer the tag between vehicles. I created this mounting system specifically for KTAG transponders, so the adhesive surface measures 3x1.2 inches. As far as I know, generic suction cups may vary in quality, but the Hillman Medium Suction Cups model 536197, which can be found at Walmart, performed well for me. To ensure a secure attachment during hot weather, it's recommended to print this holder from ABS material.
