I made this version of a tool holder for my Ender 3. There are many different versions available, but I didn't find exactly what I wanted. I used a bunch as inspiration, but followed one by odivelas most (https://www.thingiverse.com/thing:3378075). I rearranged where the tools were so it felt easier to get to them. My Ender came with a small needle, so I added a hole at the back right that holds it nicely. I also connected the two sides to form a small tray that is good for holding screws or bit you might be working with. I couldn't edit the stl file easily, so I make it from scratch in Sketchup. I have include the sketchup file is anyone wants to edit it.
I used supports, but didn't try it without.
