Nothing special here just a simple place to store your bit boxes. I am fairly new to all of this 3D printer stuff and designing my own things so it might not be 100% perfect. It fit my Milwaukee tool bit holder pretty snug but that is what I wanted. Anyway I thought it might be something worth sharing. Enjoy.
