Analog/Mechanical Load Cell

[Full info, and see it in action, here](https://bubsbuilds.medium.com/analog-mechanical-load-cell-24c0033332b3) This is intended as sort of a concept demonstrator showing an option for making a load cell with purely mechanical read out, using a series of flexural linkages. It is also a test of using 'magnetic stiffening' for these 3d printed flexures to improve their long term stiffness stability (kind of a nice feature of a load cell :) ) I used a bunch of budget, 10x4x2 magnets (18 total, 9 on either side), but feel free to experiment and please let me know if you find a better option!
