Summary

Bracket to suction cup a toll road transponder to your windshield. Our transponder came with the Velcro pre-attached so I decided to design a bracket to work with that and a suction cup.

Included are .step files of the holder, transponder and suction cup.

The suction cup came with our old transponder holder. It is approximately 42 mm (1.6) in diameter.

UPDATE: I printed my first one out of PLA. I just noticed today that it has warped and needs to be replaced. My guess is it got a little hot...

Will either reprint in ABS or High Temp PLA. May also look into adding some more structure.
