SLC Free Wideband Oxygen Sensor Controller Case

This is a 3D printed case for the open source and low cost SLC Free Wideband O2 sensor controller from 14point7 ( http://www.14point7.com/products/slc-free ). This controller will connect to a wideband oxygen sensor (Bosch LSU 4.9 or LSU 4.2) and tell you the Lambda value (Air to Fuel ratio) of your exhaust. It has a linear output, as well as a narrowband output, which emulates a narrowband O2 sensor.

I didn't like the metal standoffs included, nor having just a bare PCB exposed while using it, so I made this case. I strayed a bit from the standard build by using different connectors, so I included a middle and bottom piece for lots of variations.

If you soldered the wires directly as recommended in the instructions (or used the white Molex connectors that weren't recommended), use the _wires files. I used C-Grid III (locking shrouded) connectors, which surround the pin and make contact on multiple sides, rather than the single sided connection from the white Molex connectors
