i-Pass Windshield Mount

thingiverse

We've been experiencing issues with our i-Pass transponder's adhesive softening up and falling off or sliding down the windshield due to the hot weather lately, so I created a mount that employs three 45mm suction cups to securely hold it in place on the windshield. The transponder slides effortlessly into the mount but is held firmly in position, preventing it from slipping back out. I printed this mount using PLA, but any material would work just as well. To insert the suction cups into the mounting tabs, a bit of lubrication might be necessary since they fit quite snugly. The specifications for the suction cups I used are as follows: an upper diameter of 15mm, a neck that's 8mm in diameter and 2.5mm wide, and a bottom diameter of 18mm.
