I really liked the design of the UGMonk Analog Productivity system (https://www.kickstarter.com/projects/ugmonk/analog-the-simplest-productivity-system) but I wanted to mess around with various dimensions for other types of cards and also for different types of materials to match my various working locations.

I have designed basically two, the first is a "normal" size which has a more similar design to the original UGMonk except that I adjusted the angle of the holder to sit a bit further back and more to my liking.

The larger is basically designed to fit a full stack of cards on both the top and the bottom with the divider. This way if you buy a pack such as: https://www.amazon.com/dp/B07VZX1F21 it fits the full stack.

The divider is designed on purpose to be nice and tight so that it doesn't require any magnets or attachment systems.
