Fuse Bracket for Vehicle

I was wiring up some subs in my Scion Tc and needed a way to secure the fuse bracket to the car. There seemed to be only on spot where there is a small one inch by one inch square extrusion coming off of the air filter cover. So I took some measurements and came up with something in about a half our using sketch-up. I included the SKB file so if you have sketch-up you can modify if need be.

BE SURE TO ORIENTATE THE OBJECT AS SHOWN IN THE PIC OF IT ON THE PRINT BED.

Update 7/5/18: I have noticed after a couple days there are slight bending in the object. This is from the weight of the hood pressing down on the assembly. So I made one ending with (V2) which is for the most part the same but a half inch more shallow.
