Build me STL files/CAD for pill dispensing mechanism (Improved version of existing concept) -- 2

I have been working on a personal project which I'd like to make with 100% accuracy every-time a pill is dispensed. The mechanism is very simple but it requires me to know CAD/3D Modeling softwares which I have no experience in. I prefer someone with CAD/3D Modeling knowledge who also understands the concept from an engineering standpoint. The mechanism is very similar to (https://youtu.be/DXqMe5Xuvyw) which I have already achieved with a slight different design but I think creating a new mechanism similar to the one in video will help me achieve what I want in this project. I have a 3D printer at home so I'd like to get this project going and test it out to be able to achieve a working prototype. (Will be discussed as we build revisions)
