Dual Rocker Switch Box with JST-Connectors

Inspired by this box https://www.thingiverse.com/thing:2806903 and this connector hub https://www.thingiverse.com/thing:1487009 i created a Switch Box, which can be mounted on the lower left side of my Mega-S.

The connectors from bottom to top:

• 1) connected to the spare 12V of the PSU of my printer.
  I placed the cable more or less hidden under the printer and so on.
• 2) Directly connected (continuos power) i use for my OctoPi
• 3) and 4) Switched with the two rocker switches eg for LED stripes on the frame and LED-Lightning at the hot end.

Look at circuit.jpg (Sorry for the bad quality, i do not have a program for creating circuit diagrams)

I soldered all red respectively black ends together, two on each side, and put a heat shrink tubing over the soldered area.

Getting the 12V to the Box
Just remove the screws which are holding the bottom plate and two stands, then you can remove the bottom plate without removing the bar under the bottom.
Now you see a "open" 12 connector to which the cable is connected.
Lay it as you like or fix it with some cable strips....thats it.

I use these parts (just to let you know the sizes)

Screwing together the two parts with M3 x 12 screws.

The pictures from inside are from my first version of the box, the new published version is smaller and the walls are thinner. But the wires and the soldering are the same.

And yes, with the print shown in the first pic, i had some serious problems with my filament ;-)

Depending of the quality of your printer and the filament it might be that you have to widen the connector holes a little with a rasp (i had to...). And as the connectors are fitting really tight i glued the parts in the holes with a little bit of Super-Glue.
