+git checkout noisy_cricket
+```
+
+Connect the board and execute this:
+
+```shell
+make noisy_cricket:default:flash
+# or with the QMK tool: qmk flash -kb noisy_cricket -km default
+```
+
+## 4. Case

+- Print `upper_case.3mf`
+- Print `lower_case.3mf`
+- Print `plate.3mf` or run `make dxf` and CNC cut `plate.dxf` out of aluminium or brass
+- Optionally: CNC `weight.dxf` to further increase the weight of the case
