If you have a 3018, you know that having the circuitry out in the open will not make for long lasting operation. I have sourced an ABS box and laser’d the fan openings to cool the circuitry. Fan is included and plugs directly into the board. You’ll need to get creative on drilling the cable openings and mounting, but that is easy enough. Box internal dimensions are 110mm x 110mm x 55mm.
Comes with fan, fan hardware, lid hardware and box. Circuitry is not included. The SainSmart circuit board is 98mm x 94mm, other manufactures may use different sizes, measure yours.
