USB multimeter and ammeter

USB multimeter and ammeter I'll start by saying that this project started from the video of INewtron, an Italian Youtuber, I liked the idea and I wanted to create a 3D printed case. I initially intended to make changes but for the job it has to do it's fine. This is the link to the video :"https://www.youtube.com/watch?v=qxoFFEd62Fs&list=PLr8XA5JZPcWhYe9zLd1i-LFFG830PPLim&index=2" The material used is:2 black female panel banana plugs;1 red panel female banana plug;1 BNC connector1 x USB A Male to Female Cable;1 DC Panel Switch;One of the possible uses that I will certainly make of it is to test the absorption of smartphones. I also attached the diagram taken from the same video and it helped me a lot even though the connections are quite simple.Bye, see you next time.
