Need good-looking 3D renders of the PCB and enclosure

The tRacket website needs updated images/renders of the device. This could be done in [Blender](https://www.blender.org/) or a similar software by anyone who has the experience (or wants to try!).

* The [homepage](https://tracket.info/) has a dark "tRacket" rectangle which could be replaced by a top-down view of the enclosure
* The [sensor page](https://tracket.info/sensor/) has a render of the rev. 2 PCB in the 3D-printed case. The style of the rendering is nice; the pictured hardware is just out-of-date.

This repo has a [FreeCAD](https://www.freecad.org/) project with a 3D model of the rev. 3 PCB and the enclosure here: [https://github.com/CivicTechTO/tRacket-sensor/blob/main/hardware/pcb-rev3/tracket.FCStd](https://github.com/CivicTechTO/tRacket-sensor/blob/main/hardware/pcb-rev3/tracket.FCStd)

If you are unable to use FreeCAD, let me know and we'll figure out how to get the files you need to get started.
