I've been trying to learn how to use emachine shop software (3D CAD). I also wanted to try to design something that I thought would be at least useful to me and maybe even actually made so I chose to try my hand at an E series compatible tailcap. This is what I came up with. I took inspiration from every tailcap I've seen here on CPF, but hopefully I've achieved something different enough to be my own.
Please feel free to let me know what your thoughts are.
