Compact Temperature Controller with Completely Printed Case

An update to my previous open source temperature controller case. This design has reduced the size and includes a spot to mount a standard solid state relay. To ensure that the components, and especially the relay, don't overheat, there are ventilation grills on the top and bottom, and the SSR mounts to the side with a hole for a heatsink on the side of the case.

**Front Case** is the complete front panel and sides, with smaller grills.
I had trouble printing the grills, and wanted to try making a snap fit part, so I created:
**Front Faceplate** and **Case Sides** which snap fit together to form the front of the case, and make it easier to assemble. They have very tight tolerances, and are designed to be a permanent snap fit, but worked well in white PLA after a bit of filing on the lip of the case sides.

I have included the Autodesk Inventor files I used to create this design, as well as **Blank Faceplate**, which only has the hole for the PID controller, and **Plug Only
