Wall Plug Glorious Savior - Wallplug for car and everyday use (And Washer)

So I just spent 6 hours putting in a new Pioneer sound system on my 2005 toyota carolla, that shit was awful. I had zero instructions to follow other than youtube videos that gave me a list of directions how what to do but now how to do it. And then the stupid kit that I got didnt come with the needed screws/bolts to attach the front speakers which lead me to running back and fourth from the house to my car trying out different 3d prints until I was able to mount the speakers (semi sketchy tbh).

These models we're made for these random screws that i was using and also for the holes in the front doors of my carolla so idk if this would work for most people but let it be inspiration or material for your own work :)
