The referenced Easel project contains both parts of the car hooks. Select everything except the car outline and copy it to a new project. You will use the original file to cut the car outline and the new project to cut the front of the car.
Confirm the thickness of the material for the front of the car. I used the PVC sheets and they all varied in thickness. Secure the sheet to the waste board using double sided tape, blue tape, or clamps. I found that blue tape worked fine as long as you placed it in areas that would not get cut away.
The last step is to glue on the front and attach the hooks. I used 5 minute epoxy to bond the front to the car. Spread it very thin after mixing and try not to get it too close to the edges. Any glue that squeezes out won’t look very good. I just placed a few heavy objects on top to let the glue dry. Make sure you don’t accidentally glue anything to your car though.
Then I drilled pilot holes to attach the hooks with screws.
I used standard picture hangers on the back to hang it on the wall.
You could customize this to your liking by adding some reflective material for the windshield or carving a name or initials there as well.
