The case for the ESP32 TouchDown comes in two parts. The front is the same for every style of case you want. The back comes in four variants; a flush cover, a cover with a battery compartment, a back that has the same wedge style as FreeTouchDeck, and a similar style but at an angle of 30°.
You will also find the .f3z file so you can import the case in Fusion360 and modify it to your liking. The file called "ESP32_TouchDown_Case_with_Grid.f3z" contains the front with a 2*3 grid.
