Ender 3 v2 Tool Holder

Made the following changes to the original design:

1. Removed extra screwdriver slots, shortening the whole thing.
2. Removed Creality text as it no longer fits.
3. Removed the hook from the backside as I don't know what it's for and don't need it.
4. Deepened the grooves for the two smallest hex keys. Mine didn't fit securely in the original design as I think the geometry is different from the larger keys. However, that was too difficult for me to change so I just deepened the slots.
5. Changed the shape of the slot for the putty knife/scraper thing. Mine simply has a flat plastic piece that attaches to the blade, so I widened and deepened the slot and removed the curve from the original design.

In the end the tool holder fits all the tools that came with my Ender 3 v2.
