M5Stack tape cutter

I am into M5Stack devices nowadays. I received 3 rolls of tape among their deliveries as gift. I wanted to design a cutter so that I can utilize them easily. I have tried different versions without a blade but they were not good for cutting it easily. So I have added an opening for being able to add a cutter blade. But be aware the cutter blade stays in the open and it might be dangerous for kids usage.
