Proxmark3 RDV4 Case

I wanted a quick case to protect the RDV4, as well as obscure it a little. Many 13mhz cards/tags need some space away from the antenna to read consistently. This case provides the space required, as well as a flat surface, for me to get good reads almost all the time.

I modeled it with 1mm walls, but realized after tweaking the design twice that I was using spiral vase mode and therefore the walls were 0.65mm (using a .6 nozzle) and slicing it as a single wall because that's what I asked it to do. In the current iteration the 0.65mm wall gives it an excellent fit in spiral vase mode. If you want to make the case stiffer and go for the 1mm walls you'll likely need to tweak the model, so I included the step file.
