This is a grommet which goes over the front brake lines in a Jeep Cherokee XJ. The grommets go in the holes in the front wheel wells, where the brake line passes through from the engine bay to the wheel wells. I made these with TPU 15% infill, and 2 outer layers. They are a snug fit intentionally, so it will take a little persuasion to get them installed.
I installed these on my '01 Jeep Cherokee. I cannot confirm what other year models they will work on, but I suspect they will work on most.
The author marked this model as their own original creation.
