    Boxes for CNC electronics

    Some things I've designed. They fit the items in the photos.

    A box for that common, fancier type, 5 axis CNC breakout board.

    A box for that common, real cheap CNC breakout board.

    A box for that small board with switches and a knob to manually control speed and direction of one stepper motor.

    Nice. I also made a box for a TI switching regulator evaluation board. One that clips onto a DIN rail. I've printed it in ABS and have run into a couple of issues. Getting mounting hole spacing correct while dealing with ABS shrinkage (and corner lifting) is one problem.

    But the big one is the Repetier Slicer to create tap size holes for the screws.

    I'd really like to have the mounting posts solid but still have other parts of the boxes with 20% infill. This way the box still uses minimal plastic but I can drill a hole or drill out to tap size a small hole and then thread it. The trouble is the infill tends to allow the drill to wander into the empty spots and so my holes are either angled or pulled off center.

    Is there a way to thicken mounting posts? I noticed you just ran holes straight through and used a nut.

    Use more perimeters and more top and bottom layers. Set the top and bottom thickness to a multiple of the layer size and shell thickness to a multiple of the nozzle diameter.

    I set the bottom depth of the holes in the box bottoms low enough so they start on top of the bottom skin. Makes it easy to drill them through if needed.

    I got an Orange Pi Plus 2E. There were no boxes for it, except a crappy molded one on Ali Express. So I designed this one. http://www.thingiverse.com/thing:1916113
