Description

This is a two part FasTrak metro transponder holder that fits onto the circular shaft of my Toyota Matrix rear view mirror. I think this should be similar to Toyota Corolla's as well. Note that the fit around the rear view mirror shaft is tricky. The current design could be tightened up but be careful not to crack the clamp. The holder for the transponder is designed to be snug with the velcro stickers on the back of the transponder. If your transponder does not have those, you will have to make it thinner or put something in there for a snug fit. Also note the sketchup stl files are sometimes non-manifold so I usually fix it through netfabb and then print. The included STLs should have no problems.
