Description

My headlight for my 2017 GMC Terrain apparently had a shorted connection and melted the connector where the wiring harness connects into the headlight. I thought it would be a nice modeling exercise to try and recreate this functionally. We were able to create a new wiring harness and use some small spade connectors, which could be glued into this new bracket, to make a new connector. 

I designed this as a nice exercise and have not actually used it in my car, but I did do a test fit and it does properly fit. I just did not actually use this for any period of time and cannot vouch for how well it will hold up overtime. I can say that with PLA, the small latch arms broke off quickly, which you can see in the photos. 

 

Print with the largest area laying down on the build plate. Support is needed but can easily be cut off.
