Those boxes I got at Radio Shack. They are just small project boxes. I drilled a hole on the bottom of the box and put the stepper motor wires thru the hole. then doubleside tape to the stepper I then have another hole on the other end for the wire that comes from my controller. I wire capped on all the wires and screwed the cover to the box on. Takes the strain off the wires and looks very neat I think!
Nothing looks worse then seeing wire just hanging! I like to do a neat job. While I was waiting for my mill to arrrive I repainted my bench. Thats why it looks so clean.
