Mechanical Binary Counter

thingiverse

This is a mechanical binary counter, perfect for learning the basics of counting with binary. I got my idea from [this Reddit post](https://www.reddit.com/r/Damnthatsinteresting/comments/ab8jge/mechanical_binary_counter/), and all credit goes to the original poster for the general design, while the 3D models are mine. This system is highly expandable as you see fit, but for each "bit" you want to display, you need to print one "Number_Card.stl", one "Peg.stl", one "Flap.stl" and one "Stand.stl". For the last bit however, you only need to print a stand, number card and "End.stl". My simulation shows a two-bit counter without all of the bits because I'm lazy, but it should show the general setup for the counter. My design is optimal as it requires no additional materials other than the 3D printed parts, except maybe superglue if you want it to be more permanent. I haven't printed this yet so there may be problems with it, however feel free to download it and try it, and give me some feedback!
