The previous design was the smallest, offered the most feedback, and could pass as a wearable. Toward the end of the design process, I had another idea based on techniques I learned from every compass I made so far. I think I can eliminate the axle holder, which added a lot of size in every dimension, and it is responsible for the unwanted clattering when I shake it.
The key will be to have a spring on each end of the axle, but craft it so that it will self-align and automatically reseat if there is a severe jolt. Additionally, I can make the springs compliant mechanisms, living springs, so I can print them. Printable springs offer the ability to tune them through modeling instead of carefully cutting elastic material, which is less repeatable. I can design the living springs so they move primarily in one direction so I get less side-to-side movement, which was responsible for the clattering when I used elastic that flexed in every direction.
The 3D Printed Axle Springs will feature threaded tops, which I can use to adjust the height precisely when I install them into a threaded tube. Most of the work resides in this component, which I will model last. The rest of the components are relatively simple pieces or parts I can find commercially. I sketched the top half, but the bottom will be the same parts.
