He did the design and printing, I did the fun job of testing. We went through a lot of testing, and a lot of trial and error, but have now arrived at what I feel good using. the V4 We were originally going to print them ourselves and sell them to maintain quality etc, but with some things in life, neither my friend nor I have the time to make physicals now.
