Ender 3 Tool Holder

I moved the scraper to the back so it doesn't catch the Z carriage. Changed the USB holder to just the rectangle as I never put the cap back on. Shelled out to save material.

FYI, I didn't include the screw driver as I haven't used it yet, and I forgot to put it back in the model. I ended up just drilling an 1/8" hole after the fact and that works great.
