Audi TT MK1 Dome / Map Light Fix

thingiverse

When Audi engineers designed the map light for the MK1 TT, they cleverly engineered plastic clips that hold the dome light assembly firmly in place and used a lever-type design to secure the lens perfectly. Fast forward 20 years, however, and the plastic becomes brittle, eventually breaking. My 2001 Audi TT's dome light has been out of commission for some time now. The plastic clips that held it in place snapped off before I even had a chance to notice, causing the map light assembly to flop around loosely in the headliner. The lens itself suffered damage when one of its plastic mounting tabs broke, but the other remained intact, so I learned to live with it. While cleaning the dome light recently, I accidentally broke the remaining clip on the lens, rendering the light useless once again. It can no longer stay securely attached to the roof. Gravity takes hold, and a new light from Audi would cost around $180 - no thanks! So, I took matters into my own hands and designed a couple of small clips that are glued to both the lens and the dome light assembly, replacing the original design and holding everything in place as it should be. I've included three files: one for the little L-shaped clips that hold the dome light assembly, which glue into the channels in the light housing where the old clips once were. Hopefully, you can see this clearly in the photos provided. The other two files are for clips glued to the remaining stub on the lens - there's one for the left and one for the right, both being mirror images. These designs are incredibly easy to print. Simply lay them flat on your build plate and use ABS plastic. Avoid using PLA, as it will melt in sunlight and fail miserably. Lightly sand the surfaces and apply some epoxy to secure them in place. Use clothespins to clamp everything down while it sets. With just a few minutes of your time, you can save yourself $180 - a small price to pay for peace of mind!
