Ender 3 Pro Tool Box

The parts were designed in inch units so you'll have to scale the parts to 2,540% to make them the correct size. I used Ultimaker Cure to slice. Sometimes the parts import at 10,000 percent (really big) or 100 percent (really small). Scaling all to 2,540% will fix this.

You will need to print 2 of the Tool Box Clips in order to mount the box to the Ender 3 Pro bottom frame. The clips slide onto the box and then slide into the bottom rail (you'll need to remove the back end cap from the frame first).

I recommend printing the clips on their "side" such that support material is not needed.
