The case is very simple made out of 2 parts. The main case where the PCB will go and the back lid that will be closed with some small 1mm screws. The glass of the case is actually made out of a Fresnell plastic lens sheet so it will look cooler and also make the tubes look bigger. It was printed with black charcol color PLA using my bambulab printer. Some supports are needed for the push button area. The case has two hooks for a simple watch belt.
