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.

Yes
Supports:
No
shouldn't matter
Infill:
20
Notes:
Do not print with supports. The angle of the holder is oriented that you do not need overhangs. You will need a RAFT for the HOLDER only. Infill 20% should be fine. Clamp should be 10% infill but 3-4 shells, I think.
clamp design
The clamp settings are most important. The holder you could pretty much do anything. Note that the design is such that the fins on the clamp tighten on the holder single fin only when attached to rear view mirror shaft. This friction fit allows a variety of windshield angles. the top of the transponder hits the roof so that it does not pop out easily.

it looks like the holder experiences too much stress around the inner edge where it clamps on to rear view mirror shaft. Someone needs to redesign this for a more solid fit.
