This tool holder is everything you need to hold all the tools (+ some) that come with the Ender 3 / Pro. It slides into the top extrusion on the right side. I tried to design this to minimize tool rattle noise.

You can print it however you like, but I suggest a couple important tips for a successful print.

It should be printed 45 degrees from the bed. I've already positioned the model this way.

Enable support / 80% support overhang angle / support placement - touching build plate only / Enable support brim

Print with a part brim

If you follow those directions you will have a great chance of the print coming out perfect.

I had a small matching Philips screwdriver, so I included a holder for that.
